Question

The correct statement(s) out of the following is/are:

• A. $P_4{O}_{10}$ is used as a drying agent
• B. White phosphorus has $4\text{P}-\text{P}$ bonds
• C. In $P_4{O}_{10}$, each phosphorus atom is bonded to three oxygen atoms
• D. $P_4{O}_{10}$ hydrolyses in water and forms phosphorus acid

Answer 1

The correct option is A $P_4{O}_{10}$ is used as a drying agent

(a) Because of its great affinity for water, $P_4{O}_{10}$ is used extensively as a drying agent for gases and for removing water from many compounds.

(b) In $P_4$ structure we can see there are 6 $P-P$ bonds
(c) In $P_4{O}_{10}$, each phosphorus atom is bonded to four oxygen atoms
(d) $P_4{O}_{10}$ hydrolyses in water and forms phosphoric acid.
$P_4{O}_{10}+6H_{2}O\to 4H_{3}P{O}_4$
