Question

Consider the following statements about $P_4{O}_{10}$ and select the incorrect one.

• A. One mole of it requires 6 moles of water for complete hydrolysis
• B. It is used as a dehydrating agent
• C. Each phosphorus is tetrahedrally bonded to 4 oxygen atoms
• D. It hydrolyses in water to form phosphorus acid

Answer 1

The correct option is D It hydrolyses in water to form phosphorus acid

Each $P$ is $s{p}^3$ hybridisedandconnected to 4 oxygen atoms. It is hydrolysed by water and is used as a dehydrating agent. It contains $6P-O-P$ linkages and hence it requires 6 moles of $H_{2}O$ per mole for complete hydrolysis.
