Question

Which of the following oxyacid contains both $P-H$ and $P-P$ bond simultaneously?

• A. $H_4{P}_2{O}_5$
• B. $H_4{P}_2{O}_7$
• C. $H_4{P}_2{O}_6$
• D. None of these

Answer 1

Answer: (D)

$P-P$ linkage exists when calculated oxidation number = maximum Ox. No. (i.e. 5) for P







$\underset{\left(4\right)}{H_4{P}_2{O}_6}=$ No $P-H$ linkage.
