Question

With a change in hybridisation of the carbon bearing the charge, the stability of a carbanion increase in the order (A) s p < s p 2< s p 3 (B) sp < s p 3< s p 2 (C) s p3< s p2< s p (D) sp 2< s p< s p 3

Carbanion is electron rich species. Stability of carbanion increases with increase in

s

-character of hybrid orbitals of carbon bearing the charge.

∴ s p^{3} < s p^{2} < s p

Q. With a change in hybridisation of the carbon bearing the charge, the stability of a carbanion increase in the order

$s p < s p^{2} < s p^{3}$

$s p < s p^{3} < s p^{2}$

$s p^{3} < s p^{2} < s p$

$s p^{2} < s p < s p^{3}$

Carbanion is electron rich species. Stability of carbanion increases with increase in $s$ -character of hybrid orbitals of carbon bearing the charge.
$∴ s p^{3} < s p^{2} < s p$

Q. With a change in hybridisation of the carbon bearing the charge, the stability of a carbanion increase in the order

sp<sp2<sp3

sp<sp3<sp2

sp3<sp2<sp

sp2<sp<sp3

Carbanion is electron rich species. Stability of carbanion increases with increase in s-character of hybrid orbitals of carbon bearing the charge. ∴sp3<sp2<sp (25% s-character) (33% s-character) (50% s-character)

$s p < s p^{2} < s p^{3}$

$s p < s p^{3} < s p^{2}$

$s p^{3} < s p^{2} < s p$

$s p^{2} < s p < s p^{3}$

Carbanion is electron rich species. Stability of carbanion increases with increase in $s$ -character of hybrid orbitals of carbon bearing the charge.
$∴ s p^{3} < s p^{2} < s p$
