Why is water cosidered to polar?

Answer 1

Water is considered to be a polar molecule because of its molecular structure. It is composed of two hydrogen atoms covalently bonded to a single oxygen atom which gives it a bent molecular geometry. This shape creates an uneven distribution of electrons leaving one side of the molecule slightly more negative than the other. This uneven charge distribution creates a dipole moment making it a polar molecule with partial positive and partial negative charges.

The partial positive charge of the hydrogen atoms is attracted to the partial negative charge of the oxygen atom and vice versa. This creates a strong hydrogen bonding between the molecules making water a liquid at room temperature. These hydrogen bonds also create high surface tension in water allowing it to form droplets and hold its shape when held in the hand.
