Question
The correct decreasing order of following alkyl halides according to the rate of β - elimination reaction with alcoholic KOH will be:
(i)CH3−H|C|CH3−CH2Br
(ii) CH3−CH2−Br
(iii) CH3−CH2−CH2−Br
The correct decreasing order of following alkyl halides according to the rate of β - elimination reaction with alcoholic KOH will be:

Solution
The correct option is B (i) > (iii) > (ii)
Stability of alkene after β-elimination directly depends on the number of β-substituents.Since number of β- methyl substituent in (i) is 2, (iii) is 1 and (ii) is 0, thus the correct order of stability is:(i)>(iii)>(ii).
