COMEDK · Chemistry · 4. Chemical Bonding and Molecular Structure
The \(\mathrm{P}-\mathrm{O}\) bond order in \(\mathrm{PO}_4^{3-}\) is
- A 1
- B 1.5
- C 1.45
- D 1.25
Answer & Solution
Correct Answer
(D) 1.25
Step-by-step Solution
Detailed explanation
The structure of \(\mathrm{PO}_4^{3-}\) is \[ \begin{aligned} \text { Bond order } & =\frac{\text { Number of bonds }}{\text { Number of resonating structure }} \\ & =\frac{5}{4}=1.25 \end{aligned} \]
