Question

Among the following molecules, which contains the maximum number of $P-H$ bonds?

• A. $H_4{P}_2{O}_7$
• B. $H_{3}P{O}_2$
• C. $H_{3}P{O}_3$
• D. $H_{3}P{O}_4$

Answer 1

The correct option is B $H_{3}P{O}_2$


Hence, the maximum number of $P-H$ bonds is present in $H_{3}P{O}_2$ i.e., two $P-H$ bonds.
