In the given pair of alcohol, in which pair second alcohol is more reactive than first towards hydrogen bromide?

A

B

C

`CH_(3)-underset(OH)underset(|)(CH)-CH_(2)-CH_(3)` and `CH_(3)-CH_(2)-underset(CH_(3))underset(|)(CH)-CH_(2)-OH`

D

`CH_(3)-underset(OH)underset(|)(CH)-CH_(2)-CH_(3)` and `(CH_(3))_(2)underset(OH)underset(|)(C)-CH_(2)-CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)-underset(OH)underset(|)(CH)-CH_(2)CH_(3) overset(H^(+))(rarr) CH_(3)-underset(o+)(C)H-CH_(2)CH_(3)" "2^(@)` carbocation
`CH_(3)-underset(OH)underset(|)overset(CH_(3))overset(|)(C)-CH_(2)CH_(3) overset(H^(+))(rarr)CH_(3)-underset(o+)overset(CH_(3))overset(|)(C)-CH_(2)CH_(3)" "3^(@)` carbocation
Stability order of carbocation `3^(@) gt 2^(@)`
