1.	An organic compound X of molecular formula C2H4O2 turns blue litmus to red and gives brisk effervescence with Na2CO3 and NaHCO3. Identify X and name of the gas responsible for effervescence.
Answer» X is ethanoic acid (CH₃COOH). It is acidic and hence turns blue litmus red. It releases carbon dioxide (CO₂) when treated with Na₂CO₃ and NaHCO₃ which is responsible for effervescence. 2CH₃COOH + Na₂CO₃→ 2CH₃COONa + CO₂↑ + H₂O CH₃COOH + NaHCO₃→ CH₃COONa + CO₂↑ + H₂O
