Which of the following ion is the most stable?

Options

A. `CH_(3)CH_(2)overset(+)CH_(2)`
B. `CH_(3)overset(+)CH_(2)CH_(2)CH_(3)`
C. `CH_(3)-underset(CH_(3))underset(|)overset(+)C-CH_(3)`
D. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-overset(+)CH_(2)`

Answer

C

Explanation

The order of satbility of carbocation is
`3^(@)R^(+)gt 2^(@)R^(+) gt 1^(@)R^(+) gt overset(+)CH_(3)`
`(CH_(3))_(3)overset(+)C`, being a `3^(@)R`, is the most stable.
