Q. With a change in hybridisation of the carbon bearing the charge, the stability of a carbanion increase in the order
A) $sp < sp^{2} < sp^{3}$
B) $sp < sp^{3} < sp^{2}$
C) $sp^{3} < sp^{2} < sp$
D) $sp^{2} < sp < sp^{3}$
Explanation
(c)
Carbanion is electron rich species. Stability of carbanion increases with increase in $s -$character of hybrid orbitals of carbon bearing the charge.
$\therefore\ \ \ \ \ \ sp^{3}\ \ \ \ \ \ < sp^{2}\ \ \ < sp$
(25%s-character) (33%s-character) (50%s-character)
