Question

Identify the correct statements:

• A. $P_4{O}_{10}$ is used as a drying agent.
• B. $P_4{O}_{10}$ contains $p\pi -d\pi$ back bonding.
• C. In $P_4{O}_{10}$ each P atom is bonded to three oxygen atoms.
• D. $P_4{O}_{10}$ hydrolsyse in water forming phosphorus acid.

Answer 1

Answer: (A), (B)

The correct options are
A $P_4{O}_{10}$ is used as a drying agent.
B $P_4{O}_{10}$ contains $p\pi -d\pi$ back bonding.

$P_4{O}_{10}$ is used as a drying agent as it reacts with water and form phosphoric acid. Phosphoric acid is also hygroscopic and absorbs water to form a solution.
