Consider the following compounds (1)`CH_3CH_2CH_2CH_2OH` (2)`CH_3CH_2CHOHCH_3` (3)`(CH_3)_3COH` These compounds are dehydrated by treatment with `H_2S
Consider the following compounds
(1)`CH_3CH_2CH_2CH_2OH`
(2)`CH_3CH_2CHOHCH_3`
(3)`(CH_3)_3COH`
These compounds are dehydrated by treatment with `H_2SO_4` .The correct sequence of increasing order of the reactivity of three compounds towards dehydration is
A. 3 lt 1 lt 2
B. 1 lt 2 lt 3
C. 2 lt 1 lt 3
D. 1 lt 3 lt 2

Correct Answer - B
The increasing order of stabilities of carbonium ions is `1^@ lt 2^@ lt 3^@` . Since carbonium ion is formed as an intermediate in the dehydration of alcohol, so ease of dehydration in the increasing order is `1^@ lt 2^@ lt 3^@` alcohols.
