Question

Select incorrect option for given reaction sequence:

• A. Y(g) produces precipitate with $CuS{O}_4$
• B. Reaction of Z(aq) with $CuS{O}_4$ is a redox reaction
• C. Bond angle in $P_4<Y\left(g\right)$
• D. On heating $H_{3}P{O}_3$ it produces $H_4{P}_2{O}_7$

Answer 1

The correct option is D On heating $H_{3}P{O}_3$ it produces $H_4{P}_2{O}_7$



$3CuS{O}_4+2P{H}_3⟶C{u}_3{P}_2\downarrow +3H_{2}S{O}_4$

$H_{3}P{O}_3\stackrel{200{}^{o}C}{\to }3H_{3}P{O}_4+P{H}_3$
