Question

Which dissolving interaction is experienced when SI2 dissolves in NCl3?

Answer 1

NCl₃ has three lone pairs and one bonding pair. That makes it an AX₃E molecule.

The four electron domains give it a tetrahedral electron geometry. The lone pair makes the molecular shape trigonal pyramidal.

N and Cl have almost exactly the same electronegativities. The electronegativity difference is so small that the N-Cl bonds are nonpolar.
