A significant difference case is positive solutions to your homework questions the footprints on moon. Which of these molecules is polar? atom closest to polar or nonpolar? As both Hydrogen and Nitrogen are placed far from each other at bond angles of 180 degrees, it forms a linear shape. And so Carbon will share its remaining three electrons with Nitrogen to complete its octet, resulting in the formation of a triple bond between Carbon and Nitrogen. Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization. I have tried to make this explanation as simple as possible. This characteristic gives rise to polarity in covalent molecules.
