Which type of intermolecular force is pbr3

Dipole-dipole interactions is found in PBr₃

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces (covalent or ionic bonds)

Types of Intermolecular Forces are Dispersion, Dipole–Dipole, Hydrogen Bonding, and Ion-Dipole.

Dipole-dipole interactions are intermolecular attractions that result from two permanent dipoles interacting. This is found in PBr₃, SO₂, I₂, and CO₂.

Dipole-dipole attractions

Explanation:

PBr₃ is a trigonal pyramidal molecule.

The P-Br bonds are polar, with their bond dipoles pointing toward the Br atoms (see below).

The x-components of the dipoles cancel, but the y-components reinforce each other.

The partially negative Br atoms are attracted to the partially positive N atoms in neighboring molecules.

These dipole-dipole forces are the strongest intermolecular forces in PBr₃.
