The reagent with which the following reaction is best accomplished is 
- A \(\mathrm{H}_{3} \mathrm{PO}_{2}\)
- B \(\mathrm{H}_{3} \mathrm{PO}_{3}\)
- C \(\mathrm{H}_{3} \mathrm{PO}_{4}\)
- D \(NaHSO_{3}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{H}_{3} \mathrm{PO}_{2}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{H}_{3} \mathrm{PO}_{2}\) is the reagent that converts \(-\mathrm{N}_{2}^{+} \mathrm{Cl}^{-}\) group into H. During this process \(\mathrm{N}_{2}\) and \(\mathrm{HCl}\) gases are released.
