Question

The number of P-O bonds in $P_4O_6$ is :-

• A. 18
• B. 12
• C. 9
• D. 6

Answer 1

Answer: (B)

12

Answer 2

The structure of $P_4O_6$ consists of a tetrahedron of 4 phosphorus atoms with 6 oxygen atoms bridging each pair of phosphorus atoms. Each P atom is bonded to 3 O atoms. Total P-O bonds = 4 (P atoms) $\times$ 3 (P-O bonds per P atom) = 12.
