On reaction of Lead Sulphide with dilute nitric acid which of the following is not formed?
- a
Nitric oxide
- b✓
Nitrous oxide
- c
Lead nitrate
- d
Sulphur
Nitrous oxide
Strategy: Relate intermolecular forces and molecular mass to physical states of noble gases.
Step 1: Properties Noble gases are monoatomic and exhibit very weak dispersion forces. As the size of the atom increases (from to ), the polarizability increases, leading to relatively stronger (though still weak) London forces.
Step 2: Conclusion Matching the trend in boiling points or solubility provides the correct response.
