# Which is more stable carbonation ? ("CH"_3)_2"C"^"+""-F" or ("CH"_3)_2"C"^"+""-CH"_3 And why ?

Jan 13, 2017

The more stable carbocation is ("CH"_3)_2 stackrelcolor(blue)("+")("C")"-CH"_3.

#### Explanation:

The difference is in the $\text{F}$ and the ${\text{CH}}_{3}$ groups.

$\text{F}$ is an electron withdrawing group, and ${\text{CH}}_{3}$ is an electron donating group.

Donating electrons to a carbocation reduces its charge and makes it more stable.

∴ The second carbocation is more stable.
