Here's the breakdown:

* N (Nitrogen): Nitrogen has 5 valence electrons and forms 3 bonds (one with Hydrogen and two with Chlorine) to achieve a stable octet.

* H (Hydrogen): Hydrogen has 1 valence electron and forms 1 bond with Nitrogen.

* Cl (Chlorine): Chlorine has 7 valence electrons and forms 1 bond each with Nitrogen.

Therefore, the total number of bonds in NHCl2 is 3 (N-H, N-Cl, N-Cl) + 1 (H-N) = 4.
