is it correct?

Vocaloid · Answer

Politely disagree with A

Reminder that each bond contains 2 bonding electrons

6 bonding electrons is therefore contained in 6/2 = 3 bonds

Look for the molecule with exactly 3 bonds

Review Lewis structures when you get a chance

NF3 has nitrogen bonded to three fluorine atoms, for a total of 3 bonds. There is also a lone pair on the nitrogen.

3 bonds = 6 bonding electrons, and therefore NF3 fits the description
