Question

Analyze the propagation step in anionic polymerization. Why is head-to-tail addition favorable in this process?

Accepted Answer

It minimizes steric hindrance and allows for the stabilization of the growing chain end.

Answer

It involves the random addition of monomers, which does not affect stability.

Answer

It forms a cationic chain that is highly reactive.

Answer

It maximizes steric hindrance and destabilizes the chain end.
