Arrange the following carbanions in the increasing order of their stability
CH3, C, CH3CH2

Dear Student, 

Since Carbon has a higher electronegativity than carbon, it will provide an electron donating effect, thus leading to decrease in stability of the carbanion. Also, the presence of -R groups(Carbon containing groups) will decrease stability of the carbanion due to inductive effect(+I).

So, the correct increasing order of the given carbanions will be:

CH3CH2- < CH‚Äč3- < C-

Hope it helps.

Regards
