The stability of carbanions Figure
follows the order

  • A
    $III < \mathrm{IV} < I < II$
  • B
    I < II < IV < III
  • Correct answer
    C
    III < II < I < IV
  • D
    IV < III < II < I

Solution

(IV) is stabilized by Resonance \& $1^{\circ}>2^{\circ}>3^{\circ} \rightarrow$ stability order of carbanion

Hence, the correct answer is option: 'C'.
