Chloromethane, more commonly referred to as methyl chloride, is an organic compound categorized as a haloalkane functional group. Functional groups are atoms that control how the molecule will react with other molecues. Haloalkane functional groups consist of a carbon atom with four single bonds and one of the bonds in occupied by an element in the Halogen family; in this case chlorine. The structural formula is CH3Cl. This formula effects some of the physical properties which include the boiling point to be -22.22°C and the melting point to be -97.7°C. Other physical properties consist of a faint sweet smell, colorless gas, and it is soluble in water.
One type of reaction that produces chloromethane is a photochemical reaction. Photochemical reactions occur because light shines down upon the reaction and provides the heat and energy required to start the reaction. When the light comes into contact with diatomic chlorine, the reactions begins; Cl2 → 2Cl●. A free radical reaction follows. Free radical reactions are reactions that involve free radicals. Free radicals are singular atoms or molecules that have one unbonded electron, which is denoted with a ●, or dot, next to the element or molecule. The second step commences when one of the original radical chlorine atoms combines with methane to create a radical methyl group and hydrochloric acid; CH4 + Cl● → CH3● + H Cl. The radical methyl group then becomes an intermediate when it becomes a product along with diatomic chlorine to finally produce chloromethane and a radical chlorine;CH3● + Cl2 → CH3Cl + Cl●. Methylation takes place during this third step in the photochemical process also. Methylation is the addition or subtraction, in this case addition, of a methyl group into a re...

The sole purpose of performing the lab was to utilize aldol condensation reactions to synthesize a cyclopenta-dienone, while using UV spectrophotometry and computer visualization to further understand the dienone. In the beginning of the lab, the tetraphenylcyclopentadienone (TPCP) was synthesized using dibenzyl ketone and benzyl under extremely basic conditions. The synthesis process could be further understood by observing the mechanism portrayed in Figure 1. According to the figure, the dibenzyl ketone will first loose an alpha hydrogen to form the enolate intermediate.
Organic catalyst is another term that was noted in the movie which is used to speed up the reaction; this may have been used with the breaking down the double bonds of the polymer molecules and bond together. Radical reactions control many processes such as the formation of polymers and explosions. Elastomer was used to describe Flubber which is another word for rubber. Isotope is described as one of tow or more atoms that have the same atomic number but different atomic weights and mass number. A radioactive isotope has a half-life which is the time required for ½ of any quantity of substance to decay. The isotopes have an unstable nucleus that decays emitting gamma rays.

The compound that is formed is 17alpha-propiolic acid which is reduced to the lactone. Then the solution is oxidized and treated with thioacetic acid and chloranil that finally create spironolactone, also known as 17-hydroxy-7α-mercapto-3-oxo-17α-pregn-4-ene-21-carboxylic acid γ-lactone acetate (6). Spironolactone has a melting point of 198 degrees Celsius to 207 degrees Celsius. It is insoluble in water, but soluble in benzene, ethyl acetate, and alcohol. The solubility of Spironolactone increases with increasing polarity of the solvent. The IR spectrum of spironolactone shows a conjugate carbonyl group and a lactone carbonyl present in the structure

In his situation, Mr. Euglena waits for the sun to get higher in the sky because he needs enough sun light to convert into energy in photosynthesis. The light reaction is the first stage of photosynthesis which requires light. With the sunlight, four pigments in his chloroplasts absorb the sunlight. These four pigments are carotenes, xanthophylls I and II, and chlorophyll b. These pigments will then convert the sunlight to chemical energy, which then transfers to chlorophyll a. Chlorophyll a then splits six water molecules (6 H2O) into twelve hydrogen atoms (12 H) and three oxygen molecules (3 O2). The coenzyme NADP then holds the product of twelve hydrogen atoms (12 H) as 6 NADPH2 to carry to the next process. The three oxygen molecules (3 O2) are then released into the air as a byproduct. The light reaction must happen a second time in order for the second phase of photosynthesis, the dark reaction, to occur. The same cycle of the light reaction then takes place. The result of two lig...
The late sixties were a time filled with sex, drugs, and rock and roll. A huge part of American culture at the time was focused around these three things. Musicians possessed a tremendous amount of social influence, and like wise, society put a lot of emphasis on the lives and attitudes of musicians. Of the rock groups from this time period, the Beatles were by far the most influential. The British rock group was probably the most catalytic band in rock and roll history. Although they came together in the shadow of the Beatles, another band of that era was Jefferson Airplane. Jefferson Airplane was deemed the first of the San Francisco psychedelic rock groups. Jefferson Airplane was always considered to be a psychedelic rock group, but it was not until later in their existence that the Beatles fell into this category as well. Both groups earned this title for their creative style of rock as well as for their experimentation with drugs. Each of these groups wrote songs that alluded to drug use at one time or another. Two of the most criticized songs from these bands are Lucy in the Sky with Diamonds by the Beatles, and White Rabbit by Jefferson Airplane. White Rabbit is a song latent with drug references. The connection with drugs in Lucy in the Sky with Diamonds is not as clear. Although John Lennon claims that he had no intention of making references to LSD in his song, the abstract lyrics and metaphoric language invite drug connotation. Lucy in the Sky with Diamonds and White Rabbit mirror each other in their association with LSD and their allusions to Alice in Wonderland, but looking into these songs more deeply it is obvious that both artists were writing about escape; escaping reality.

The first stage is the light dependent reaction(it was called the light reaction), and the chloroplast traps light energy and changes it into chemical energy which is (NADPH) and (ATP), these are two molecules used in the second stage of photosynthesis. In the second stage, this is called the light-independent reaction (it was called the dark reaction), NADPH gives the hydrogen atoms to help form glucose, and ATP gives the energy for reactions used to make glucose. The stages are literal meaning of photosynthesis, to build with light. In the light-dependent reaction photosynthesis depend on the energy flow started by light energy. Electrons are small particles that move in a specific orbit around the nuclei of atoms and have a small electrical charge. Light energy causes the electrons in chlorophyll and other light-trapping pigments to increase up and out of orbit; the electrons automatically fall back into place, releasing energy, or vibrating energy, as they go, all in millionths of a
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...

And the light – independent reaction takes place in the stroma of chloroplasts carbon dioxide molecules [ CO2 ] are needed during this stage of photosynthesis . CO2 is added to a cycle of chemical reactions to build larger molecules , Energy from the light –dependent reactions is used in the reactions . A molecule of a simple sugar is formed . The sugar, usually glucose [ C6H12O6 ] , Stores some of the energy that was captured from sunlight .
