Sol. (i)A on reaction with alcoholic KOH gives a

mixture of two isomeric alkenes B and C.

C6H13Cl C6H12 + C6H12

Isomers

(ii) Mixture of B and C on ozonolysis gives four

products i.e.,

(1) CH 3 CHO (2) C 2 H 5 CHO

(3) CH 3 COCH 3 (4)

(iii) Since B and C are of six carbon atoms each

and thus, product formed on ozonolysis for

each alkene must contain in all six carbon atoms. That

is why one alkene gives CH 3 CHO +

and other alkene gives C 2 H 5 CHO and CH 3 COCH 3

Thus alkenes are :

(iv) Since B and C are formed from halide A, thus halide should be :

Reactions involved are as :

3-chloro-2-methyl pentane

+

2-methyl pentene-2 4-methyl pentene-2
