An aromatic ether is not cleaved by $$HI$$ even at $$525\,K.$$ The compound is
A.
$${C_6}{H_5}OC{H_3}$$
B.
$${C_6}{H_5}O{C_6}{H_5}$$
C.
$${C_6}{H_5}O{C_3}{H_7}$$
D.
$${\text{Tetrahydrofuran}}$$
Answer :
$${C_6}{H_5}O{C_6}{H_5}$$
Solution :
Due to greater electronegativity of $$s{p^2}$$ - hybridized carbon atoms of the benzene ring, diaryl ethers are not attacked by nucleophiles like $${I^ - }.$$
