Question

X is a smallest optically active alkanol. On dehydration it can form by number of alkenes

Answer 1

The smallest optically active alkanol is methanol (CH3OH)

Answer 2

Answer:

An optically active alcohol is that which can rotate plane of plane polarized light. It can rotate plane of plane polarized light towards right (clockwise, dextrorotatory) or towards left (anticlockwise, laevo rotatory).

2-Butene is obtained by dehydration of 2-Butanol

$CH_3-CH_2-COH-CH_3--->CH_3-CH=CH-CH_3$

Number of alkenes =2+1 =3

Because in Butanol cis and trans show the optical activity.

Hence ,

Hence ,Butanol is a smallest optically active alkanol .On dehydration it can form by 3 number of alkenes that is Butene .
