Optically active `CH_(3) -CH_2-overset(OH)overset(|)(CH)-CH_3`was found to have lost its optical activity after standing in water containing a few drops of acid, mainly due to the formation of

Options

A. `CH_3 - CH_2 -CH= CH_2`
B. `CH_3 -CH=CH-CH_3`
C. `CH_3 - overset (CH_3) overset(|) CH - CH_2 -OH `
D. `CH_3 -CH_2 -CH_2 -CH_2 -OH`

Answer

B

Explanation

`CH_3 -CH_2 - underset( OH) underset(|) -CH_3`
` underset("(Dehydration )")overset("Few drops of acid ") to CH_3 - CH =CH-CH_3`
The above optically acitve compound undergo dehydration with few drops of acid and form stable alkene through the formation of stable carbocation .
