Question

The stability of carbanions in the following (A) (i) > (ii) > (iii) > (iv) (B) (ii) > (iii) > (iv) > (i) (C) (iv) > (ii)>(iii)>(i) (D) (i) > (iii) > (ii) > (i)

The carbanion with more s-character is more stable. Thus, the order of stability is R C ≡ overset ominus C > C 6 H 5 ominus>R2 C = overset ominus C H>R3 C - overset ominus C 2

Q. The stability of carbanions in the following

(i) > (ii) > (iii) > (iv)

(ii) > (iii) > (iv) > (i)

(iv) > (ii)>(iii)>(i)

(i) > (iii) > (ii) > (i)

The carbanion with more s-character is more stable. Thus, the order of stability is
$RC \equiv C ⊖ > C_{6} H_{5}^{⊖} > R_{2} C = C H ⊖ > R_{3} C - C ⊖_{2}$

The carbanion with more s-character is more stable. Thus, the order of stability is RC≡C⊖>C6​H5⊖​>R2​C=CH⊖>R3​C−C⊖2​

The carbanion with more s-character is more stable. Thus, the order of stability is
$RC \equiv C ⊖ > C_{6} H_{5}^{⊖} > R_{2} C = C H ⊖ > R_{3} C - C ⊖_{2}$
