उत्तर
| Methane (non polar) | HCL (polar) |
| Covalent compounds are non polar when shared pairs of electron(s) are equally distributed between the two atoms. | Covalent compounds are said to be polar when the shared pair of electrons are not at equal distance between the two atoms. |
| No charge separation takes place. The covalent molecule is symmetrical and electrically neutral. | Charge separation takes place. The atom which attracts electrons more strongly develops a slight negative charge while the other creates a little positive charge. |
| \[\begin{array}{cc} \ce{H}\\ \ce{H:\underset{..}{\overset{..}{C}} :H}\\ \ce{H} \end{array}\] |
\[\ce{H:\underset{..}{\overset{..}{Cl}}}\] |
