Is SeCl6 polar or nonpolar?

Home  > Chemistry Questions > SeCl6 polar or nonpolar?

SeCl6, also known as selenium hexachloride, is a nonpolar molecule. Although the individual Cl-Se-Cl bonds are polar due to the electronegativity difference between them.

The shape of SeCl6 is perfect octahedral, due to this, the dipole moment of each individual bond gets canceled by others leading to a net dipole moment of zero and making this overall molecule (SeCl6) nonpolar.

Examples: H2O, NH3, etc.Examples: CH4, SeCl6, etc.

In summary, polar molecules have a net dipole moment, meaning they have a positive and negative end due to the electrons being shared unequally between atoms.

While nonpolar molecules have no net dipole moment and electrons are shared equally between atoms, resulting in no positive or negative ends.
