Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Dipole moment depends on the presence of polar bonds and molecular symmetry.

• Nitrobenzene → polar due to the nitro group, so μ ≠ 0
• p-Chloronitrobenzene → unlike groups at para position do not cancel completely, so μ ≠ 0
• m-Dichlorobenzene → dipole vectors do not cancel, so μ ≠ 0
• o-Dichlorobenzene → dipole vectors also do not cancel completely, so μ ≠ 0

Correct Answer: (A), (B), (C), (D)
