each reaction’s product are formed under the constraints of stereochemistry and regiochemistry. In a general elimination reaction‚ an atom or group of atoms is removed from a carbon‚ along with an adjacent hydrogen‚ resulting in a C=C π bond forming between the α-carbon (where the leaving group was attached) and the β-carbon (where the adjacent hydrogen bond was attached). The first

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

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

COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in it‚ meaning higher energy content • Lignite: softest‚ low in carbon‚ but high in oxygen & hydrogen • Bituminous: All of the above found in similar amounts Coal is mined out of the ground using various methods
