Select the WRONG statement about polar molecules.
Options
- APolar molecules have permanent dipole moment.
- BA molecule in which centre of mass of positive charges does not coincide with the centre of mass of negative c
- CPolar molecules have symmetrical shape.
- DPolar molecules act as tiny electric dipoles.
Correct answer
C. Polar molecules have symmetrical shape.
Step-by-step solution
In a polar molecule, the centre of mass of positive charges does not coincide with the centre of mass of negative charges. This separation of charges results in a permanent electric dipole moment, causing the molecule to act as a tiny electric dipole. Because the charge distribution is uneven, polar molecules generally have an asymmetrical shape. Symmetrical molecules (like CO ₂ or CH ₄ ) have their centres of positive and negative charges coinciding, resulting in a net zero dipole moment, making them non-polar. Th
