Answer 1

In a molecule of pyrophosphoric acid, the number of P-OH, P=O and P-O-P bonds/moiety(ies) respectively are 4, 2 and 1.

Explanation:

According to the structure of pyrophosphoric acid (H₄P₂O₇), it contains 4 P-OH bonds, 2 P=O bonds, and 1 P-O-P linkage. Each phosphorus atom is tetrahedrally surrounded, forming one double bond with oxygen and two OH groups, while being joined by an oxygen bridge.
