Question
Q1. Write reaction equations for the reaction of propene with (a) hydrogen (Pt catalyst), and (b) bromine. Q2. Write reaction equations for the reaction of cyclohexene with (a) HCl, and (b) with water (H2SO4 catalyst). Assignment: Write equations for ozonolysis of alkenes
Solution
Q1. (a) Propene reacts with hydrogen in the presence of a platinum catalyst to form propane. The reaction equation is: C3H6 + H2 -> C3H8
(b) Propene reacts with bromine to form 1,2-dibromopropane. The reaction equation is: C3H6 + Br2 -> C3H6Br2
Q2. (a) Cyclohexene reacts with HCl to form chlorocyclohexane. The reaction equation is: C6H10 + HCl -> C6H11Cl
(b) Cyclohexene reacts with water in the presence of a H2SO4 catalyst to form cyclohexanol. The reaction equation is: C6H10 + H2O -> C6H12O
Assignment: Ozonolysis of alkenes involves the reaction of an alkene with ozone to form organic compounds in which the multiple carbon–carbon bond has been replaced by a carbonyl group. The general reaction is: R1R2C=CR3R4 + O3 -> R1R2CO + R3R4CO
