Answer

Answer:

  • Water molecules are polar.
  • Water molecules undergo hydrogen - bonding.
  • Water molecules have a bent geometry.

Explanation:

Step1: Polarity of water

Oxygen is more electronegative than hydrogen. In a water molecule ($H_2O$), the unequal sharing of electrons between oxygen and hydrogen atoms creates a dipole moment, making water polar.

Step2: Hydrogen - bonding

The partially positive hydrogen atoms in water molecules are attracted to the partially negative oxygen atoms of neighboring water molecules, leading to hydrogen - bonding.

Step3: Molecular geometry

In a water molecule, the central oxygen atom has two bonding pairs and two lone pairs of electrons. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the electron - pair repulsions result in a bent molecular geometry.
