The chemicals used for preparing acetophenone via Friedel-Crafts acylation are:
$(A)$ $C_6H_6$
$(B)$ $CH_3COCH_3$
$(C)$ $CH_3COCl$

$m$-Bromoanisole reacts with $NaNH_2$ in liquid $NH_3$ to give mainly:

What is obtained by the reaction of toluene with chlorine in the presence of iron and in the absence of light?

Reaction of alkyl halides with aromatic compounds in the presence of anhydrous $AlCl_3$ is known as

"The presence of an electron-withdrawing group $\left( -NO_2 \right)$ at the ortho and para positions in haloarenes increases the reactivity of haloarenes towards nucleophilic substitution reactions." Prove this with an example.

Compare the rate of Electrophilic Substitution Reaction $(ESR)$ for the following compounds:
