an organic compound of molecular formula C2 H6 O on oxidation with acidified potassium dicarbonate gives an acidic compound B. Compound A reacts With B on warming presence of concentrated H2So4 to give a sweet smelling substance C. what are A,B and C?
Answers
Answer:
A is ethanol B is ethanoic acid and C is ester
Explanation:
A hac formula C2H6O which in structural formula is CH3CH2OH hence is ethanol
on reacting with potassium dicarbonate it release ethanoic acid
so B is ethanoic acid
ethanol react with ethanoic acid in presence ofH2SO4 to release ester
Compound A reacts with compound B in presence of H₂SO₄ to give sweet smelling substance C.
So we conclude that C is an ester.
An ester is produced when a carboxylic acid and alcohol reacts.
Compound A on oxidation gives compound B. We know alcohols on oxidation with strong oxidising agents gives us carboxylic acids. So we can conclude A is an alcohol and B is carboxylic acid.
The formula of A is C₂H₆O
It has two carbon atoms. So it is ethanol (ethanol has formula C₂H₅OH which is same as C₂H₆O )
Ethanol on oxidation gives ethanoic acid (CH₃COOH), which is our compound B
Ethanol and ethanoic acid gives the ester ethyl acetate (CH₃COOC₂H₅)
So
A is ethyl alcohol or ethanol (IUPAC)
B is acetic acid or ethanoic acid (IUPAC)
C is ethyl acetate or ethyl ethanoate (IUPAC)
