The reaction of an aryl halide with sodium metal in the presence of dry ether to form a biphenyl is known as:

The rate of reaction of $NaOH$ with the following compounds follows the order:
$I$: $1$-fluoro-$2$-nitrobenzene
$II$: $1$-fluoro-$3$-nitrobenzene
$III$: $1$-fluoro-$4$-nitrobenzene

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

$C_6H_6$ $\xrightarrow[\text{Conc. } H_2SO_4]{\text{Conc. } HNO_3} B$ $\xrightarrow{\text{Sn + HCl}} C$ $\xrightarrow[0-5^\circ C]{HNO_2} D$ $\xrightarrow{HBF_4} E$ $\xrightarrow{\Delta} F$
$F$ will be

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

Haloarenes are less reactive than haloalkanes and haloalkenes towards nucleophilic substitution reactions. Explain.
