(a)
Interpretation:
The dipole moment of the anti-conformation of
Concept introduction:
The dipole moment is defined as the charge separation between two atoms or ions in a covalent or ionic bond. If the value of dipole moment is zero, then the molecule is said to be non-polar, and if the value of dipole moment is not zero, then the molecule is said to be polar and possess permanent dipole moment.
If any structure is symmetrical, then overall dipole moment will be zero, and the bond becomes non-polar. Also, a bond can be considered polar if there is some electronegativity difference between the atoms.
