A) \[S{{O}_{2}},\,C{{O}_{2}}\]
B) \[C{{O}_{2}},\,C{{O}_{2}}\]
C) \[S{{O}_{2}},\,NO\]
D) \[S{{O}_{2}},\,N{{O}_{2}}\]
Correct Answer: B
Solution :
Benzene sulphonic acid and p-nitrophenol react with \[NaHC{{O}_{3}}\] and evolve \[C{{O}_{2}}\]gas. Because benzene sulphonic acid and p-nitrophenol are stronger acids, so they are capable of to evolve\[C{{O}_{2}}\]with\[NaHC{{O}_{3}}\].\[HCO_{3}^{-}+{{H}^{+}}\xrightarrow{{}}{{H}_{2}}O+C{{O}_{2}}\uparrow \]You need to login to perform this action.
