Question

Which is/are correct statements about $P_4{O}_6$ and $P_4{O}_{10}$?

• A. Both form oxyacids $H_{3}P{O}_3$ and $H_{3}P{O}_4$ respectively.
• B. In $P_4{O}_6$ each P is joined to four O and in $P_4{O}_{10}$ each P is joined to four O atoms.
• C. Both (A) and (B).
• D. None of the above.

Answer 1

The correct option is A Both form oxyacids $H_{3}P{O}_3$ and $H_{3}P{O}_4$ respectively.

$P_4{O}_6+6H_{2}O\to 4H_{3}P{O}_3$
$P_4{O}_{10}+6H_{2}O\to 4H_{3}P{O}_4$
