Question

Which compound has the greater dipole moment?

Short answer

When there is a charge separation in a system, a dipole moment occurs.As a result, they can occur in both ionic and covalent connections.

Dipole moments are caused by differences in electronegativity between two chemically connected atoms.

Step-by-step solution

Definition of dipole moment

When there is a charge separation in a system, a dipole moment occurs.As a result, they can occur in both ionic and covalent connections.

Dipole moments are caused by differences in electronegativity between two chemically connected atoms.

a. Which compound has the greater dipole moment?

because the C-Cl dipoles oppose each other so they have opposite direction of dipole moments.

b. Which compound has the greater dipole moment?

because a sp² carbon has a higher electronegative value than a sp³ carbon Thus, in the combination on the left, the C-CH₃ and C-Cl dipoles support each other, resulting in a larger dipole, whereas in the compound on the right, they oppose each other, resulting in a lower dipole.
