The reaction of 1-phenylpropene with bromine shows syn addition. The reason for the loss of stereospecificity due to the phenyl group should be determined. Concept introduction: Alkenes are unsaturated hydrocarbons having a double bond between carbon atoms. Thus, it shows addition reactions. Some examples of addition reactions of alkenes are hydrohalogenation, halogenation, catalytic hydrogenation, acid-catalyzed hydration, hydroboration-oxidation, oxymercuration-demercuration, etc. The addition reactions mainly occur with the formation of carbocation as an intermediate.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
