Explanation:

Question 4

In \(H_2O\) (water), the oxygen atom is more electronegative than hydrogen atoms. The molecular geometry is bent, leading to an unequal distribution of electron density. This creates a dipole moment, so \(H_2O\) is a polar molecule.

For \(NH_3\) (ammonia), the nitrogen atom is more electronegative than hydrogen atoms. The molecular geometry is trigonal pyramidal, resulting in an unequal sharing of electrons and a net dipole moment, making \(NH_3\) a polar molecule.

Molecules with bent molecular geometry (like \(H_2O\)) have a net dipole moment due to the asymmetric arrangement of bonds (and lone pairs in some cases), leading to polarity. So a molecule with bent geometry is typically polar.

Answer:

polar molecule
