An organic compound (A) of molecular formula C2H6O liberates H gas with

Question

An organic compound (A) of molecular formula C₂H₆O liberates H₂ gas with metallic sodium and gives (B). (B) on reaction with methyl bromide produces (C) of molecular formula C₃H₈O. (C) on reaction with excess III produces (D) and (E). Identify A, B, C, D and E and explain the reactions involved

Answer 1

1. An organic compound (A) reacts with Na metal and liberates H₂ gas means it must be an alcohol. From the molecular formula it is identified as ethanol – CH₃ – CH₂OH (A).

2. Ethanol on reaction with Na metal to produce sodium ethoxide as (B) with liberation of H₂ gas.

3. Sodium ethoxide on reaction methyl bromide undergo Williamson’s synthesis to produce methoxy ethane as (C).

4. Methoxy ethane on reaction with excess HI will give Ethyl iodide and Methyl iodide as (D) and (E).
