Why are water molecules polar?

This is a short answer type question as classified in NCERT Exemplar

Water molecules are polar because in the gas phase water is a bent molecule with a bond angle of 104.5°, O-H bond length of 95.7 pm. Oxygen is more elsectronegative  (EN = 3.5 ) than hydrogen (EN= 2.1 ) hence, O-H bond is polar . In the water molecule, two polar O-H nonds area present which are held together at an angle of 104.5 . Due to the resultant of these two dipoles, water molecule is polar and has an dipole moment of 1.84 Debye.
