Question

DIPOLES FORM AT EACH BOND BETWEEN HYDROGEN AND OXYGEN IN A WATER MOLECULE BECAUSE _

Answer 1

Answer:

Dipole form on each bond between hydrogen and oxygen atom in water molecule because of the electronegativity difference

between hydrogen and oxygen.

Explanation : Electronegativity means attraction of shared pair of electron toward itself in the covalent bond. Those atoms having same electronegativity values, the shared electron remain in the center whereas those atoms having different electronegativity values, the shared pair of electron is attracted by the atom having high value of electronegativity. In water molecule, electronegativity of oxygen is higher so it attracts electron pair towards itself and forms negative pole and hydrogen aquire positive pole.
