Polar bond in hydrogen chloride molecule. Animation of the sharing of electrons (dots and crosses) between a hydrogen atom (H) and a chlorine atom (Cl) to form a molecule of hydrogen chloride (HCl). This is an example of covalent bonding, with the single bond shown here formed by a shared electron pair consisting of an electron from each atom. The outer electron shell of each atom is shown as a blue ring. The second part of the animation shows the effect of electronegativity. Chlorine exerts more of a pull on the electron pair than the hydrogen atom. This causes the covalent bond to become polarised, creating a dipole moment. There is a partial negative charge (delta minus) at the chlorine atom and a partial positive charge (delta plus) at the hydrogen atom. It is this polarity of the bonding that makes hydrogen chloride (a gas) highly soluble in polar solvents such as water, forming hydrochloric acid. | |
