Question

a carbon compound X turns blue litmus to red and has a molecular formula C2 H4 O2 . identify X and draw its structure. Write chemical equation for the reaction and name of the product formed in each case when X reacts with(a)ethanol in the presence of conc. H2SO4 (b) sodium carbonate

Answer 1

X is acetic acid or CH3COOH

Structure is in the picture

(a) Acetic acid reacts with ethanol to form ester in presence of conc.H2SO4
conc. H2SO4
CH3COOH + C2H5OH ----------------------> CH3COOC2H5 + H2O
Product formed is Ethyl ethanoate or ethyl acetate.

(b) Na2CO3 + 2CH3COOH ---------> 2CH3COONa + H2O + CO2
Carbon dioxide gas is evolved.
