Explain why BeCl2 molecule has a zero dipole moment although the Be--H

1.	Explain why BeCl2 molecule has a zero dipole moment although the Be--H bonds are polar
Answer» Be have two electrons in valence shell it forms Leonard shape molecules since bonds are in opposite in direction so the net dipole moment zero but in Be--H due to high electronegativity of Be Berilium attracts an electron of hydrogen so Be gets partial negative charge and H gets partial positive charge hence Be--H is a polar molecule
