(a) H₂O is one of the following molecules contains no π - bond.
- All the molecules given in the option have 'O' atom but in H₂O ,the H-atom does not have any vacant orbital for π - bonding.
- All the other atom of SO₂ ,NO₂ and CO₂ have vacant orbital for π - bonding.

'H₂O' molecules contains no pi - bond.
Option: A
Explanation:
- According to chemistry, pi bonds are termed as covalent chemical bonds where the orbital with 2 lobes in one atom overlap with an orbital of another atom.
- This overlapping process occurs in lateral fashion. These electrons are supposed to have 0 electron density at a shared nodal plane.
- The nodal plane passes through 2 bonded nuclei. These bonds could be formed in double and triple bonds.
- In H2O, the H atom has no vacant orbital for pi – bond. So it does not have any pi – bond.
