Consider the following reaction:
(Major Product)
If B is an oxoacid of phosphorus with no P–H bond, then A is
- a
White
- b✓
Red P
- c
- d
Red P
Strategy: Consider the physical state and interatomic forces of noble gases.
Step 1: London Dispersion Forces Noble gases consist of single atoms held by weak dispersion forces. The strength of these forces increases with the size and polarizability of the atom.
Step 2: Conclusion The properties like boiling point and enthalpy of vaporization increase from to . Matching this trend provides the answer.
