Which one of the following is not used as an initiator in ionic polymerisation?
- A \(\mathrm{NaNH}_2\)
- B \(\mathrm{SnCl}_2\)
- C \(\mathrm{AlCl}_3\)
- D \(\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2\)
Answer & Solution
Correct Answer
(D) \(\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2\)
Step-by-step Solution
Detailed explanation
In ionic polymerisation ions/ion pairs have ends with ionic center \(\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2\) 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.
