Which one of the following is not used as an initiator in ionic polymerisation?

Options

  1. ANaNH ₂
  2. BSnCl ₂
  3. CAlCl ₃
  4. D( C ₆ H ₅ CO )₂ O ₂

Correct answer

D. ( C ₆ H ₅ CO )₂ O ₂

Step-by-step solution

In ionic polymerisation ions/ion pairs have ends with ionic center ( C ₆ H ₅ CO )₂ O ₂ is a covalent compound and will not give any ionic center for chain initiation, thus can not be used as an initiator in ionic polymerisation.
