Which compound most likely contains polar covalent bonds? NaCl AlF3 Br2 NF3

belka [17]

Answer: The correct answer is $NF_3$

Explanation:

In $NF_3$ molecule, there are three bond pairs and one lone pair present in the molecule. In a molecule, lone pair present on the nitrogen atom will have a dipole moment in upward direction where as total dipole moment formed by three fluorine atoms will be more in magnitude and it will be directed in downward direction which means that the net dipole moment will be in downward direction. As shown in image attached.

Hence, covalent bond present between nitrogen and fluorine will become polar in nature.

So, the correct answer is $NF_3$ .
