Question

Water $\left(H_{2}O\right)$ is liquid while all other molecules of equivalent and even higher molecular weight are present in gaseous state because of

• A. Covalent bonding between Hydrogen and Oxygen.
• B. Electrostatic attraction among water molecules.
• C. Hydrogen bonds.
• D. Ionic bonds.

Answer 1

The correct option is C Hydrogen bonds.

In $H_{2}O$ there is hydrogen bonding because oxygen has a high electronegativity(only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding, which results liquid form of water.
