Question

Select the WRONG statement about polar molecules.

• A. Polar molecules have permanent dipole moment.
• B. A molecule in which centre of mass of positive charges does not coincide with the centre of mass of negative charges is a polar molecule.
• C. Polar molecules have symmetrical shape.
• D. Polar molecules act as tiny electric dipoles.

Hint:

A polar molecule has an asymmetric charge distribution, not a symmetrical shape.

Answer 1

The Correct Option is C

Step 1: Check each statement against the definition
Polar means the positive and negative charge centres are separated.

Step 2: Spot the odd one
Only (C) conflicts with this, since symmetry cancels dipoles. Option (C).

Final Answer:
Option (C) is wrong. \[ \boxed{\text{(C)}} \]
