Correct order of stability of carbanion is
Options
- AC B D A
- BA B C D
- CD A C B
- DD C B A
Correct answer
D. D C B A
Step-by-step solution
As we know compound (4) is aromatic and the compound (1) is anti-aromatic. Hence compound (4) is most stable and compound (1) is least stable among these in compound (2) and (3) carbon atom having charge is sp ^3 hybridised. On the basis of angle strain theory compound (3) is more stable than compound (2).
