Observe the following reaction
\(\begin{aligned} & \text { a } \mathrm{P}_4(\mathrm{~s})+\mathrm{b}^{-} \mathrm{OH}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \rightarrow \\ & \qquad \mathrm{cPH}_3(\mathrm{~g})+\mathrm{dH}_2 \mathrm{PO}_2^{-}(\mathrm{aq})\end{aligned}\)
\(\mathrm{a}, \mathrm{b}, \mathrm{c}\) and \(\mathrm{d}\) are respectively
- A 1,3,3,1
- B \(1,3,2,3\)
- C \(3,1,3,1\)
- D \(1,3,1,3\)
Answer & Solution
Correct Answer
(D) \(1,3,1,3\)
Step-by-step Solution
Detailed explanation
The balanced equation is :- \(\mathrm{P}_4(\mathrm{~s})+3 \mathrm{OH}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{PH}_3(\mathrm{~g})+3 \mathrm{H}_2 \mathrm{PO}_2^{-}\)(aq.) Thus, \(a=1, b=3, c=1\) and \(d=3\)
