Question

Why do electron-withdrawing groups stabilize the carbanion in anionic polymerization?

Accepted Answer

They delocalize the negative charge through resonance.

Answer

They donate electrons to the carbanion.

Answer

They increase the electrophilic character of the monomer.

Answer

They decrease steric hindrance around the carbanion.
