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 .

11.; (a) Similar to alkanes, hydrogen gas can undergo radical bromination according to the reaction below. Propose a chain-reaction mechanism for this reaction, including an initiation step, propagation steps, and two plausible termination steps. The homolytic bond dissociation energy for Br-Br is 46 kcal·mole', for H-Br is 88 kcal'mole and for H-H is 104 kcal'mole'. hv H-H + Br-Br 2 H-Br (b) Calculate the overall AH for the above propagation steps (show all work).

Substitutions on aromatic rings are generally carried out by electrophilic substitution, but for the synthesis of phenolic compounds and alkoxy benzene it is carried out by nucleophilic substitution, explain why this is so .

Free-radical chlorination of hexane gives very poor yields of 1-chlorohexane, while cyclohexane can be converted to chlorocyclohexane in good yield. How do you account for this difference?
