The following transformation proceeds through:

The reaction of an aryl halide with an alkyl halide and sodium metal in dry ether to form substituted aromatic compounds is known as:

What is formed when chlorobenzene reacts with ammonia in the presence of $Cu_2O$ in xylene at $570 \ K$?

The major product formed in the Friedel-Crafts acylation of chlorobenzene is $p-$chloroacetophenone. Identify the correct structure of the major product.

Rank the following compounds in order of decreasing rate of reaction with alkoxide ion $(CH_3CH_2O^{-})$ in a nucleophilic aromatic substitution reaction:
$1$. $1$-bromo-$2$-nitrobenzene
$2$. $1$-bromo-$3$-nitrobenzene
$3$. $1$-bromo-$2,4$-dinitrobenzene
$4$. $1$-bromo-$3,4$-dinitrobenzene

$(i)$ chlorobenzene is mono-nitrated to $M$.
$(ii)$ nitrobenzene is mono-chlorinated to $N$.
$(iii)$ anisole is mono-nitrated to $P$.
$(iv)$ $2-$nitrochlorobenzene is mono-nitrated to $Q$.
Out of $M$,$N$,$P$ and $Q$,the compound that undergoes reaction with $aq. NaOH$ fastest is:
