A) \[CH_{3}^{-}\]
B) \[C{{H}_{3}}CH_{2}^{-}\]
C)
D)
Correct Answer: C
Solution :
Key Idea: Electron donating groups (e.g., R) increases the electron density and thus make carbanion unstable. Electron withdrawing groups (e.g.,\[N{{O}_{2}}\]) take away the electrons and thus stabilises the carbanion. \[CH_{3}^{-}\]and\[C{{H}_{3}}\overset{-}{\mathop{C}}\,{{H}_{2}}\]andare unstable due presence of electron withdrawing alkyi group is stabilised by electron withdrawing effect of\[N{{O}_{2}}\]group.You need to login to perform this action.
