Question

# Among the following compounds, the one which can be dehydrated most easily is:

A
CH3CH2CH3|C|OHCH2CH3
B
CH3CH2CH2C|OHHCH3
C
CH3CH2CH2CH2CH2OH
D
(CH3)2CHCH2CH(OH)CH3

Solution

## The correct option is A $$CH_{ 3 }-CH_{ 2 }-\overset { \overset { CH_{ 3 } }{ | } }{ \underset { \underset { OH }{ | } }{ C } }-CH_{ 2 }CH_{ 3 }$$The compound which can be easily dehydrated will form most stable carbocation after removal of $$H_{ 2 }O$$ molecule. Since stability of carbocation follows 3 degree> 2 degree> 1 degree, so, compound $$A$$ is most easily dehydrated.Option A is correct.Chemistry
