Question

On nitration, the major product that chlorobenzene gives is:

• A. $1$-chloro-$4$-nitrobenzene
• B. $1$-chloro-$3$-nitrobenzene
• C. $1,4$-dinitrobenzene
• D. $2,4,6$-trinitrobenzene

Answer 1

Answer: (A)

$1$-chloro-$4$-nitrobenzene

Since, $Cl$ group attached to benzene is ortho and para directing, so it forms o- and p-chloronitrobenzene as products.

Here the major product is p-chloronitrobenzene because of the resonance.
