Question

Write equations for the following:

1. a substitution reaction between 2-bromopropane and KI;

2. an addition reaction between cyclohexene and Cl2

3. an addition reaction between 2-propanone and H 2(Ni metal is a catalyst).

Answer 1

1. CH3-CHBr-CH3 + KI ------->CH3-CHI-CH3 + KBr

2-bromopropane                2-iodopropane

2. C6H10 + Cl2 -------.>C6H10 Cl2

cyclohexene               1,2-diclorocyclohexane

3. CH3COCH3 + H2 (Ni metal as catalyst) ----->CH3-CH(OH)-CH3

2-propanone                                                     2- propanol
