Question

A) an organic compound a with molecular formula c 2 h 4 o 2 on reaction with sodium metal na releases a gas b which readily catches fire . a on r eact ing with ethanol in the presence of concentrated sulphuric acid gives a s weet smelling substance c used in making perfumes. write a balanced chemical equation to represent the se two reactions and identify the compounds a, b and

c.

Answer 1

Hey folk !!

Here's the answer you are looking for

a's molecular formula is C2H4O2 and it reacts with a metal to give a gas.

So, a must be an acid and the organic acid possible with this molecular formula is ethanoic acid, that is CH3COOH.

Ethanoic acid reacts with Na to give out gas (b) H2 with readily catches fire.

Then, ethanoic acid and ethanol (C2H5OH) react to form ester, sweet smelling and used in making perfumes. So, c is ester CH3COOC2H5.
