Question

When following molecules are arranged in decreasing order of boiling point, N 2 ​ is present on n th position. Find ′ n ′ . CO, H₂O, H₂, N₂, He

TestHub · Accepted Answer

The boiling point depends on intermolecular forces. H₂O has hydrogen bonding (strongest). CO has dipole-dipole forces. N₂, H₂, and He have London dispersion forces (LDF). LDF strength increases with molecular size/electrons.

Order: H₂O > CO > N₂ > H₂ > He.

N₂ is in the 3rd position.
