Question

Two compounds ‘A’ and ‘B’ have the same molecular formula C4H8O2. Compound ‘A’ is an acid and compound ‘B’ has a fruity smell. Suggest (i) chemical formulae and (ii) the structural formulae of compounds A and B. Name the functional group of compound B. What name would you give to the relationship between the compounds A and B

Answer 1

answer A is saponification and B is esterification

Answer 2

A is Butanoic acid while B is Methyl proponate with molecular(C4H8O2).
Structural formula of both the compounds are
CH3CH2CH2COOH (Butanoic acid) &
CH3CH2COOCH3 (Methyl proponate)
Functional group present in compound B is
an ester (R-COO-R).
THE relationship between them is that they contain 1 molecule of Oxygen (O2).
Also both the compound react with NaOH a base
