NH₂Cl - Chloramine:

First draw the Lewis dot structure:

Electron geometry: tetrahedral. Hybridization: sp³

Then draw the 3D molecular structure using VSEPR rules:


Decision:
The molecular geometry of NH₂Cl is trigonal pyramidal with asymmetric charge distribution on the central atom.
Therefore this molecule is polar.
