Verified By Collegedunia
The Correct Option isC
Solution and Explanation
In case of $NH_3$, the orbital dipole due to lone pair is in the same direction as the resultant dipole moment of the three $ N - H$ bonds whereas in $NF_3$ the orbital dipole is in the direction opposite to the resultant dipole moment of three $N?

Top Questions on Chemical bonding and molecular structure
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
Types of Chemical Bonds:
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
Ionic Bonds - Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
Covalent Bonds - Compounds that contain carbon commonly exhibit this type of chemical bonding.
Hydrogen Bonds - It is a type of polar covalent bonding between oxygen and hydrogen wherein the hydrogen develops a partial positive charge
Polar Bonds - In Polar Covalent chemical bonding, electrons are shared unequally since the more electronegative atom pulls the electron pair closer to itself and away from the less electronegative atom.
