Solution

The correct option is A Decreases electron density at meta position
In electrophilic aromatic substitution, the nitro group is an electron withdrawing group which decreases electron density at meta position. So, $N O_{2}$ group is meta dijecting.

Q. Ethyl group

(- C H_{2} C H_{3})

in ethylbenzene increases electron density at which of the following positions?

Assertion (A): - $N O_{2}$ group is benzene ring deactivating and m - directing group

Reason (R): - $N O_{2}$ group with draws electron density from benzene ring and makes ortho and para positions more electron deficient than meta position

Q. Which of the following group(s) when attached to a benzene ring decreases the electron density at ortho/para positions?

Q. Although chlorine is an electron withdrawing group, yet it is ortho-para directing in electrophilic aromatic substitution reactions. Why?
