Water is a polar molecule. Explain what is meant by the term polar using water as an example.

Answers

jane
A polar molecule has partially positive and partially negative charges on opposite sides of the molecule. This is due to the difference in electronegativity of the bonding atoms, whereby the more electronegative atom pulls the shared electron pair towards itself resulting in partial negative charge around it and a partial positive charge on the other atom. The electrons are hence not equally shared.

A water molecule is comprised of, two hydrogen atoms and an oxygen atom. Oxygen is more electronegative than the hydrogen; hence it pulls the electron pair towards itself resulting in a partial negative charge around it and a partial positive charge around the hydrogen atoms.
