Question

An organic compound A has molecular formula C2H6 O. A on addition with oxygen gives B gives effervescence with baking soda a) identify A and B b) write the reaction of B with baking soda

Answer 1

The solution is as follows:

Organic compound A is Ethanol - CH₃CH₂OH which undergoes the following oxidation:

CH₃CH₂OH $\stackrel{\left[O\right]}{\to }$ CH₃COOH
To give Ethanoic acid (B).

When ethanoic acid reacts with baking soda:

CH_​3COOH + NaHCO₃ $\to$ CH₃COO^-Na⁺ + CO₂ + H₂O
