Compound ‘A’ (C8H16O2) on hydrolysis gives an acid ‘B’ and an alcohol ‘C’. It shows that ‘A’ is an ester. Since the oxidation of alcohol ‘C’ also gives the acid ‘B’ indicates that ‘B’ and ‘C’ both contain same number of carbon atoms, i.e, four carbon atoms each and same arrangement of atoms. Formation of but-1-ene on dehydration of ‘C’ indicates it to be butan-1-ol, so the possible structure for ‘A’ could be
The various reactions involved are written as follows :
