							Hello student,

There are two effects:
(a)Polarizability
(b)Molecular Size

(a) Polarizability

Polarizability is the ease of distorting an electron cloud.

A phosphorous atom is bigger than a nirogen atom. Itsvalence electronsare much further from the nucleus, so they are not tightly held. A nearby dipole can distort the electron cloud much more than it can distort that of a smaller atom.

(b) Molecular Size

Even if the atoms are the same size, bigger molecules have stronger London dispersion forces. There are more electron clouds to distort.

All the Best
Regards
