MCQ

Water $\ce{(H_2O)}$ 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.
✓
Hydrogen bonds.
D
Ionic bonds.

✓

Answer

Correct option: C.

Hydrogen bonds.

In $\ce{H_2O}$ 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.
