A

`CH_(3) - underset(CH_(3)) underset(|)(C ) H - CH_(2) OH`

B

`CH_(3)- overset(CH_(3)) overset(|) underset(CH_(3)) underset(|)( C) - OH`

C

`CH_(3) - CH_(2) - CH_(2)- CH_(2) OH`

D

`CH_(3) - underset(CH_(3)) underset(|)(C ) H - CH_(2) - CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3) overset(CH_(3)) overset(|) underset(CH_(3))underset(|) ( C) - OH to underset("(Carbonium ion)") (CH_(3) - overset(CH_(3))overset(|)underset(CH_(3))underset(|)( C^(+)))`
Carbonium ion most stable due to +I effect of three methyl groups and hyperconjugation by `9 alpha` hydrogens
