The molecule is not polar. Covalent bonds occur when one atom shares electrons with another. The relative electronegativities of the bonded atoms is H < C < Cl, and so the bond moments all point toward the Cl end of the molecule and sum to yield a considerable dipole moment (the molecules are relatively polar). Although, some molecules contain polar bonds, the molecule may be non-polar. For each molecule we will determine its molecular geometry, electron domain geometry, polarity, and the hybridization on the central atom. Make sure to include things you could use on a test to help you. In general, pyramid-shaped and V-shaped molecules are said to be polar. In this blog post, we will look at the Lewis dot.

Electronegativity is the ability for an atom in a molecule to attract electrons to itself. HF has hydrogen bonding, which is a stronger force, so it will have the higher boiling point. The remaining carbon valence electrons then occupy these molecular orbitals in pairs, resulting in a fully occupied (6 electrons) set of bonding molecular orbitals. A diatomic molecule that consists of a polar covalent bond, such as \(\ce{HF}\), is a polar molecule.
