Question

Which of the substances has polar interactions (dipole–dipole forces) between molecules?

Answer 1

Answer:

CHCl3 has dipole-dipole interactions.

Explanation:

Trichloromethane has a electric dipole moment permanently pointing along the line parallel with the Hydrogen carbon axis.Dipole-dipole interactions are said to be intermolecular force of  attractions that is formed from two permanent dipoles interacting.

These type of interactions  are occurring when one of the partially charged formed molecule are  being attracted to an opposite partially charged molecule  nearby . The molecules align in a state that the positive end of one of the molecule  gets interacting with the negative end of the another molecule.
