Question #f91dc

1 Answer

Nitrogen trichloride would have a trigonal pyrimidal shape and an AXE designation of #AX_3E#.

Explanation:

Nitrogen atoms have 5 valence electrons. The nitrogen atom has three unpaired electrons which will be shared with a chlorine atom (which has 7 valence electrons) to form a single bonds. This means the molecule has a central nitrogen bonded to three chlorine atoms each by a single covalent bond.

The other two valence of the nitrogen are a non-bonding pair and give the molecule its trigonal pyrimidal shape. This shape is predicted by using VSEPR theory.
