Question

What is correct order of rate of nitration of the following compounds?
$\underset{A}{C_6{H}_{5}C{H}_3}$ $\underset{B}{C_6{H}_6}$ $\underset{C}{C_6{D}_6}$ $\underset{D}{C_6{T}_6}$ $\underset{E}{C_6{H}_{5}B{r}_3}$ $\underset{F}{C_6{H}_{5}N{R}_3}$ $\underset{G}{C_6{H}_{5}NM{e}_2}$.

• A. G $>$ A $>$ B $>$ C $>$ D $>$ E $>$ F
• B. G $>$ B $>$ C $>$ D $>$ A $>$ F
• C. G $>$ A $>$ B $=$ C $=$ D $>$ E $>$ F
• D. G $>$ A $>$ B $>$ C $=$ D $>$ E $>$ F

Answer 1

Answer: (A)

G $>$ A $>$ B $>$ C $>$ D $>$ E $>$ F

Nitration is an electrophilic aromatic substitution reaction.The $+I$ effect increases the rate of nitration whereas the $-I$ effect decreases the rate of nitration.

Therefore,the correct order of rate of nitration is $G>A>B>C>D>E>F$
