Question

Identify the correct reason for zero dipole moment.

• A. The molecule may be homoatomic
• B. There may be a dative bond in the molecule
• C. The molecule may be heteroatomic and symmetric
• D. There may be Ione pairs in the molecule

Answer 1

Answer: (A), (C)

The correct options are
A The molecule may be homoatomic
C The molecule may be heteroatomic and symmetric

The correct reason for zero dipole moment include the following.
(A) The molecule may be homoatomic. The electronegativity difference between atoms will be zero.
(B) The molecule may be heteroatomic and symmetric. The individual bond dipoles will cancel out in this case.
