Show Answer
Answer:
Correct Answer: D
Solution:
All cations are expected to act as Lewis acid since they are electron deficient in nature.
However cation such as $ N{a^{+}},\ {K^{+}} $ etc.
(Inert gas configuration) have a very little tendency to accept electrons.
Therefore they do not acts as lewis acids in friedel Craft’s reaction.
