Methane (non-polar)
covalent compound
HCl (polar)
covalent compound
Covalent compounds are said to be non-polar when shared pair of electrons are equally distributed between the two atoms.Covalent compounds are said to be polar when shared pair of electrons are unequally distributed between the two atoms.
The covalent molecule is symmetrical and electrically neutral.The atom which attracts electrons more strongly develops a slight negative charge while the other develops a slight positive charge.
