Show Answer
Answer:
Correct Answer: A
Solution:
$ \underset{\begin{smallmatrix} ,Methyl \\ ,carbanion \end{smallmatrix}}{\mathop{CH{{_3^{{}}}^{-}}}},>,\underset{\begin{matrix} {} \\ \begin{matrix} {} \\ 1^{o} \\ \end{matrix} \\ \end{matrix}}{\mathop{R-CH{{_2^{{}}}^{-}},>}},\underset{,2{}^\circ }{\mathop{R-\underset{R,}{\mathop{\underset{|}{\mathop{C{H^{-}}}},}},}},>,\underset{3{}^\circ ,}{\mathop{R-,\underset{R}{\overset{R}{\mathop{\underset{|}{\overset{|}{\mathop{{C^{-}}}}},}}},}}, $
