BeCl2 (Beryllium Chloride) is a non-polar molecule. This is because of its linear shape and the equal distribution of electron density around the central Beryllium atom.
In BeCl2, Beryllium forms two single bonds with Chlorine atoms. The molecule adopts a linear geometry due to the sp hybridization of the Beryllium atom. The two Chlorine atoms are placed symmetrically on either side of the Beryllium atom, resulting in a bond angle of 180 degrees.
Since the electronegativity difference between Beryllium and Chlorine is not significant enough to create a dipole moment, the molecule does not have a net dipole. Therefore, BeCl2 is considered a non-polar molecule.
