The reaction of toluene with $Cl_2$ in the presence of $FeCl_3$ gives predominantly

The reaction of $1-^{14}C$-chlorobenzene with $NaNH_2/NH_3$ proceeds via a benzyne intermediate. Two benzyne intermediates are formed. Reaction with the amide ion can occur in two different directions for each benzyne, giving three possible products in a $1:2:1$ ratio. Asterisk $(*)$ refers to $^{14}C$. Which of the following represents the major product$(s)$ $(A)$?

What is the intermediate compound formed when chlorobenzene is treated with fused $NaOH$ under pressure?

Assertion : $p-$nitroacetophenone $(p-O_2N-C_6H_4-COCH_3)$ is prepared by Friedel-Crafts acylation of nitrobenzene.
Reason : Nitrobenzene easily undergoes electrophilic substitution reaction.

The reaction of $2,6-$dideutero-fluorobenzene with $NaNH_2$ in liquid $NH_3$ gives:

Replacement of $Cl$ of chlorobenzene to give phenol requires drastic conditions,but chlorine of $2,4-$dinitrochlorobenzene is readily replaced because:
