addition: Bromination of (E) Stilbene Introduction: In this lab we used the greener approach‚ which involves the addition of bromine across a double bond. When bromine reacts with E-stilbene (trans-1‚2-diphenylethene)‚ two new chiral carbons are created from the sp2 carbons‚ therefore 3 different dibrominated stereoisomers are possible: meso-(1R‚2S)‚ or the raceminc mixture-(1R‚2R) or (1S‚2S)-dibromo-1‚2-diphenylethane (Gilbert‚ 2010). When the bromination ion intermediate proceeds through a stereospecific

of alcohol affect the rate of evaporation‚ represented by the change in temperature over time‚ measured using a temperature probe? Research/Abstract Alcohol is an organic compound in which the hydroxyl functional group‚ OH‚ is bound to a carbon atom. Its carbon center should be saturated; it should have single bonds to three other atoms. The different types of alcohols are determined by the kinds of CH2 groups while the number of CH2 groups there are tells you the volume of the alcohol. The acyclic

Polymerase chain reactions are the specific terms used in stating different compounds and sates of the carbon compound which are specially used in a particular branch of chemistry called the organic chemistry. Polymerase chain reactions are the specific reactions which take place between several carbon compounds under particular circumstances. These invariably tough reaction chains are a part of the study of organic chemistry and thus the chain reactions are considerably hard to remember or to be

Summer Assignment – AP Biology – Chapters 2-5 Chapter 2 1. CHNOPS are the six most crucial elements in most macromolecules. Name them. Carbon‚ Hydrogen‚ Nitrogen‚ Oxygen‚ Phosphorous‚ Sulfur. 2. Create a chart and state how many bonds each of the CHNOPS elements can form. Carbon | Hydrogen | Nitrogen | Oxygen | Phosphorous | Sulfur | 4 | 1 | 3 | 2 | 3 or 5 | 2 | 3. Create a Venn Diagram to compare and contrast polar covalent bonds‚ nonpolar covalent bonds‚ and ionic bonds.

the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different organic compounds that supply us with fuel for energy and the carbon attoms needed to build and repair the

an alkane have been replaced by halogen atoms‚ fluorine‚ chlorine‚ bromine or iodine. In carbon-halogen bond‚ halogens have significantly greater electronegativities than carbon except iodine. In result‚ this group is polarized so that the carbon is electrophilic and the halogen is nucleophilic. Halogenoalkanes can be classified depending on the halogen atom position on the chain of carbon atoms. The carbon which is attached with the halogen atom is linked up with only one other alkyl group in primary
