Select the correct statement about polar bonds and dipole moments.


a. A linear diatomic molecule AX has a dipole moment equal to the sum of the electronegativities of A -- X.

b. The dipole moment for a polyatomic molecule equals the vector sum of the individual bond moments.

c. The electrons in a polar covalent bond spend more time near the least electronegative atom in the bond.

d. A polyatomic molecule which contains one or more polar bonds always has a molecular dipole moment.

e. A dipole moment quantifies the separation of charge in a molecule using the number of lone pairs on each atom.

Respuesta :

Answer:

e

Explanation:

The correct statement about polar bonds and dipole moments is A. A linear diatomic molecule AX has a dipole moment equal to the sum of the electronegativities of A -- X.

It should be noted that a dipole moment refers to the product of partial charge and the distance that separates the charge in the polar covalent bond.

In a dipole moment, the linear diatomic molecule AX has a dipole moment that is equal to the sum of the electronegativities of A -- X. The electrons in a polar covalent bond do not spend more time near the least electronegative atom in the bond.
