In a normal covalent bond, the bond pair is shared equally. Ina polar covalent bond, the more electronegative atom pulls the bond pair towards itself, creating a partial negative charge on it. And a partial positive charge on the other atom. Symbols δ+ and δ- indicate the polarity of the H-Cl bond. (b) The dipole is represented by an arrow with a cross at the tail. The cross is near the δ+ end and the arrowhead coincides with the δ-. Any covalent bond between atoms of different elements is a polar bond, but the degree of polarity varies widely.***Covalent bond in which electrons are not shared equally. This occurs when one atom has a higher electronegativity than the atom it is sharing with.-Whenever two different atoms form a covalent bond, a polar bond is formed-Atoms with a greater attraction for electrons has a partial negative charge, and the other atom has a partial positive charge The hydroxyl group is polar. There is a partial negative charge (d-) on the oxygen atom and a partial positive charge (d+) on the hydrogen of the hydroxyl group. Alcohols boil at higher temperature than alkanes of similar MW. The higher boiling point is due to hydrogen bonding. If not enough electrons exist to meet the octet rule using single bonds, then double or triple bonds between two atoms are required. If short by two electrons, try a double bond, and if short by four electrons, try a triple bond or two double bonds.
