Vedclass · Answer

(A) The dehydration of alcohols proceeds via the formation of a carbocation intermediate.The ease of dehydration depends on the stability of the carbocation formed.The stability order of carbocations is: $3^\circ > 2^\circ > 1^\circ$.$I$: $CH_3-CH_2-CH_2-OH$ ($1^\circ$ alcohol)$II$: $(CH_3)_2CH-OH$ ($2^\circ$ alcohol)$III$: $(CH_3)_3C-OH$ ($3^\circ$ alcohol)$IV$: $CH_3-CH_2-OH$ ($1^\circ$ alcohol)Comparing the $1^\circ$ alcohols,$CH_3-CH_2-CH_2-OH$ $(I)$ is slightly more reactive than $CH_3-CH_2-OH$ $(IV)$ due to the inductive effect of the propyl chain.Thus,the order of ease of dehydration is $III > II > I > IV$.

The order of ease of dehydration of the following alcohols is:
$I$: $CH_3-CH_2-CH_2-OH$
$II$: $(CH_3)_2CH-OH$
$III$: $(CH_3)_3C-OH$
$IV$: $CH_3-CH_2-OH$
