Bond Length and Bond Angle Comparison

Question

P–O bond order of H₂PO₂^–1 < HPO₃^–2 and P–H bond length H₂PO₂^–1 < HPO₃^–2

P–O bond order of H₂PO₂^–1 > HPO₃^–2 and P–H bond length H₂PO₂^–1 > HPO₃^–2

P–O bond order of H₂PO₂^–1 < HPO₃^–2 and P–H bond length H₂PO₂^–1 > HPO₃^–2

P–O bond order of H₂PO₂^–1 > HPO₃^–2 and P–H bond length H₂PO₂^–1 < HPO₃^–2

$\frac{3}{2} = 1.5 > \frac{4}{3} = 1.33$

(P–O) Bond order

P–H bond length >

(P–O) Bond order (H₂PO₂¯) $↑$ , %s in (P–O) $↑$ , %s in (P–H) $↓$ so Bond length in (H₂PO₂¯) is greater than HPO₃^–2
