Vedclass · Answer

(C) The correct order of stability is given by option $(C)$.$(1)$ Carbanion stability: The stability of carbanions depends on the hybridization of the carbon atom bearing the negative charge. The electronegativity order is $sp > sp^2 > sp^3$. As the $s$-character increases, the electronegativity of the carbon atom increases, making it better at holding the negative charge. Thus, the stability order is $CH \equiv \mathop {\ddot C}\limits^\Theta (sp) > CH_2 = \mathop {\ddot C}\limits^\Theta H (sp^2) > CH_3 - \mathop {\ddot C}\limits^\Theta H_2 (sp^3)$. Option $(A)$ shows the reverse of this order.$(2)$ Radicals: Option $(B)$ refers to radicals, where stability is governed by hyperconjugation and resonance, not just hybridization.$(3)$ Acetate vs Phenoxide: Option $(C)$ compares the stability of acetate ion $(CH_3COO^-)$ and phenoxide ion $(C_6H_5O^-)$. In acetate, the negative charge is delocalized over two equivalent oxygen atoms, whereas in phenoxide, it is delocalized over one oxygen and the aromatic ring. The acetate ion is more stable due to equivalent resonance structures.$(4)$ Carbocations: Option $(D)$ compares a secondary carbocation with an oxygen-stabilized primary carbocation. The oxygen-stabilized carbocation is more stable due to the $+M$ effect of the oxygen atom.
