Question

Why is water a polar molecule?

Answer 1

Water is a polar molecule because it has a net dipole moment.

Explanation:

Water $\left(H_{2}O\right)$ is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom.
