The oxoacid of phosphorus that is easily obtained from a reaction of alkali and white phosphorus and has two P–H bonds, is
- a
Phosphonic acid
- b✓
Phosphinic acid
- c
Hypophosphoric acid
- d
Pyrophosphorus acid
Phosphinic acid
Strategy: Identify isostructural pairs among noble gas and halogen species.
Step 1: Structural Analysis Two species are isostructural if they have the same geometry and number of lone pairs. For example, and are both linear with 3 lone pairs on the central atom.
Step 2: Conclusion The pair identified in the question as isostructural or non-isostructural provides the answer.
