Why water is more polar than carbon tetra chloride?

Answer 1

Carbon tetrachloride, CCl4, is non-polar- with a zero dipole moment. The C-Cl bonds are polar because of the electronegativity difference between C an Cl however because of the tetrahedral symmetry of the molecule the bond dipoles cancel.

In water, H2O, a molecule with a bent shape the bond dipoles and lone pair dipoles do not cancel so the molecule has a net dipole moment.

Answer 2

Water is more polar than carbon tetrachloride because water has a higher difference in electronegativity between its hydrogen and oxygen atoms, resulting in a stronger partial positive and negative charge. Carbon tetrachloride, on the other hand, has a symmetrical tetrahedral structure with chlorine atoms that cancel out any polarity, making it nonpolar.
