Question

A carbon compound X turns blue Litmus to Red and has the molecular formula C2 H4 O2 identify X write chemical equation for the reaction and name the products formed in each case when X reacts with ethanol in the presence of concentrated H2 S o4 sodium carbonate

Answer 1

As the compound C2H4O2 is capable of converting ​ blue litmus red, therefore it should be an acid.
In organic, generally carboxylic acids, phenols and sulphonic acids are acididc in nature. As the molecular formula does not includes sulphur therefore the probablity of sulphonic acids si negligible.
For phenols, the minimum number of carbon present should be six. Therefore the given compound should be carboxylic acid.
The structure of X is CH3COOH and its IUPAC name is Ethanoic acid.
A) when X reacts with ethanol in presence of sulphuric acid is as follow:-

B) The recation of acetic acid with sodium carbonate is as follow:-
2CH3COOH + Na2CO3 --> 2CH3COONa + CO2 + H2O

Answer 2

The compound X is acetic acid -CH3COOH.or ethanol

Ethanol in the presence of concern. H2SO4:-- CH3COOH+ ch3ch2oh----> CH3COOC2H5.( In presence of H2SO4).

Acetic acid with sodium carbonate:- CH3COOH + Na2CO3 ------> CH3COOH + co2 + H2O
