What is the correct Lewis structure for carbononitridic chloride (CNCl) ?

For the Lewis structure, we find the total valence electrons:

N = 5

C = 4

Cl = 7

= 16

Next, since Carbon is least electronegative, we will put it in the middle of the structure.

Nitrogen will share 3 of its electrons with Carbon, resulting in a total of 6 electrons shared between Carbon and Nitrogen (triple bond)

Total electrons shared between C and Cl will be 2
