Explanation / Answer
Polar and non polar molecules can be identified by many ways. If there is net dipole moment in the molecule, the molecule will ne polar. If the dipole moment is zero, the molecule will be non polar. Also polarity can be identified on the basis of the electronegativity difference between the atoms in the molecule.
The type of hybrid orbitals used by the central atom in a given molecule can be identified from the lewis structure of the molecule. With the help of lewis structure of the molecule, we can easily identify the shape of the, molecule and with the help of shape we can find the corrresponding hybridization of the molecule and thus the hybrid orbitals used by the central atom in a given molecule can be identified.
