Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following covalent compounds has a chemical formula of NF3?
A
Dinitrogen tetrahydride
B
Dinitirogen pentoxide
C
Nitrogen tribromide
D
Nitrogen trifluoride
Explanation: 

Detailed explanation-1: -Nitrogen trifluoride has the chemical formula NF3 N F 3 .

Detailed explanation-2: -Both BF3 and NF3 are covalent compounds. BF3 is non polar while NF3 is polar.

Detailed explanation-3: -Nitrogen trifluoride (NF3) is a synthetic inorganic chemical. It is manufactured by the reaction of hydrochloric acid (HCl) and ammonia (NH3). It is toxic, odorless, colorless, non-flammable, and is an oxidizing gaseous substance at room temperature and atmospheric pressure1.

Detailed explanation-4: -Hint: Both boron trifluoride, $BF 3$ and nitrogen trifluoride, $NF 3$are formed by covalent bonding that means the bonds in these compounds are formed by sharing of one or two pairs of valence, electrons. Covalent bonding is very common in compounds formed by combining two non-metals.
