Question

The molecule having the largest dipole momemt is

Answer 1

For example, NaCl has the highest dipole moment because it has an ionic bond (i.e. highest charge separation). In the CH 3Cl molecule, chlorine is more electronegative than carbon, thus attracting the electrons in the C—Cl bond toward itself

Answer 2

$\mathcal{\huge{\red{Hii\: Buddy\:!!!}}}$..

⭐ The dipole moment occur between two ions is an ionic bond or between atoms in a covalent bond; dipole moments arise from difference as in electronegativity..

so, the molecule having the largest dipole moments is ionic bond...
