Q. In which reaction, polysubstitution takes place:

 1902  223 Hydrocarbons Report Error

Solution:

Only - can be substituted to the benzene ring in the presence of anhydrous and produce (Toluene).
This is Friedel Craft's Alkylation reaction.
But in the absence of anhydrous can be substituted to the benzene ring. In Friedel Craft's Alkylation reaction, monoalkyl derivative readily undergoes further alkylation to produce polysubstituted derivatives.
Hence, polysubstitution can take place in this reaction.
