An organic compound ‘A’ of molecular formula C 2 H 4 O 2 turns blue litmus red and gives brisk effervescence with NaHCO 3 . Identify ‘A’ and give chemical reaction.

Question

Philoid · Accepted Answer

Given that A turns blue litmus red. So A is acidic in nature.

Brisk effervescence with NaHCO₃ indicates carbon dioxide as one of the products.

The molecular formula of A contains 2 oxygen atoms. So the compound is likely to be a carboxylic acid (general molecular formula is C_nH_2nO₂)

Here n=2 and hence the compound A is ethanoic acid. The reaction is given by:

CH₃COOH + NaHCO₃→ CH₃COONa + H₂O + CO₂

An organic compound ‘A’ of molecular formula C2H4O2 turns blue litmus red and gives brisk effervescence with NaHCO3. Identify ‘A’ and give chemical reaction.

An organic compound ‘A’ of molecular formula C₂H₄O₂ turns blue litmus red and gives brisk effervescence with NaHCO₃. Identify ‘A’ and give chemical reaction.
