Select the 'WRONG' statement about polar molecules.
Options
- AA molecule in which centre of mass of positive charges does not coincide with the centre of mass of negative c
- BThey have permanent dipole moment.
- CThey act as tiny electric dipoles.
- DThey have symmetrical shape.
Correct answer
D. They have symmetrical shape.
Step-by-step solution
A polar molecule is one in which the centre of mass of positive charges does not coincide with the centre of mass of negative charges. Because of this separation of charges, polar molecules possess a permanent electric dipole moment and act as tiny electric dipoles. For a molecule to be polar, its individual bond dipoles must not cancel each other out, which typically requires an asymmetrical shape. Symmetrical molecules generally have a net zero dipole moment and are non-polar. Therefore, the statement that polar
