When benzene sulphonic acid and pp-nitrophenol are treated with NaHCO3\mathrm{NaHCO}_3, the gases released respectively areWhen benzene sulphonic acid and p -nitrophenol are treated with NaHCO_3 , the gases released respectively areWhen benzene sulphonic acid and p -nitrophenol are treated with NaHCO_3 , the gases released respectively are

Options

  1. ASO2,NO2\mathrm{SO}_2, \mathrm{NO}_2
  2. BSO2,NO\mathrm{SO}_2, \mathrm{NO}
  3. CSO2,CO2\mathrm{SO}_2, \mathrm{CO}_2
  4. DCO2,CO2\mathrm{CO}_2, \mathrm{CO}_2

Correct answer

D. CO2,CO2\mathrm{CO}_2, \mathrm{CO}_2

Step-by-step solution

 Benzene sulphonic acid and p-nitrophenol react with NaHCO3 and evolve CO\text{ Benzene sulphonic acid and p-nitrophenol react with } \mathrm{NaHCO}_{3} \text{ and evolve } \mathrm{CO}}_{2}  gas. <imgsrc="/api/proxy−image?url=https\text{ gas. }<img src="/api/proxy-image?url=https%3A%2F%2Ffirebasestorage.googleapis.com%2Fv0%2Fb%2Fquantrexacademy-app.firebasestorage.app%2Fo%2Fquestions%252Ffigs%252Fpyq%252Fjee_advanced%252FVYAE7Q7eQIqgFrITxHedCdwWvz6pLzQ0SOd5pTlVftE.original.fullsize.png%3Falt%3Dmedia&clean=1&v=wm2" data-qx-orig-src="https://firebasestorage.googleapis.com/v0/b/quantrexacademy-app.firebasestorage.app/o/questions%2Ffigs%2Fpyq%2Fjee_advanced%2FVYAE7Q7eQIqgFrITxHedCdwWvz6pLzQ0SOd5pTlVftE.original.fullsize.png?alt=media" data-qx-storage-src="https://firebasestorage.googleapis.com/v0/b/quantrexacademy-app.firebasestorage.app/o/questions%2Ffigs%2Fpyq%2Fjee_advanced%2FVYAE7Q7eQIqgFrITxHedCdwWvz6pLzQ0SOd5pTlVftE.original.fullsize.png?alt=media"> \\ Because benezene sulphonic acid and pp-nitro phenol are stronger acids with H2CO3\mathrm{H}_2 \mathrm{CO}_3 (i.e., H2O+CO2\mathrm{H}_2 \mathrm{O}+\mathrm{CO}_2 ) so, they are capable to evolve CO2\mathrm{CO}_2 with NaHCO3\mathrm{NaHCO}_3.
