Question

Correct order of stability of carbanion is a b c d (A) c > b > d > a (B) a > b > c > d (C) d > a > c > b (D) d > c > b > a

Answer: D

💡 Solution & Explanation

As we know compound (d) is aromatic and the compound (a) is anti-aromatic. Hence compound (d) is most stable and compound (a) is least stable among these in compound (b) and (c) carbon atom of that positive charge is sp3 hybridised they on the basis of angle strain theory compound (c) is more stable than compound (b).  > > >   . .
