Consider the following carbanions 1. CH3- overset ominusCH2 2. CH2= overset ominusCH 3. CH≡ overset ominusC Correct the order of stability of these carbanions in decreasing order is (A) 1 > 2 > 3 (B) 2 > 1 > 3 (C) 3 > 2 > 1 (D) 3 > 1 > 2

Stability of carbanion (when hybridisation of overset ominusC is different) is directly proportional to S character. Stability propto s% <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-kivkkcyqwqkw.png" />

Q. Consider the following carbanions

$1.$ $C H_{3} - C ⊖ H_{2}$ $2.$ $C H_{2} = C ⊖ H$ $3.$ $C H \equiv C ⊖$

Correct the order of stability of these carbanions in decreasing order is

1 > 2 > 3

2 > 1 > 3

3 > 2 > 1

3 > 1 > 2

Stability of carbanion (when hybridisation of $C ⊖$ is different) is directly proportional to S character.

Stability $\propto$ s%
