उत्तर
C2H5OH (ethanol) and CH3COOH (ethanoic acid) are the compounds which can react with each other, in the presence of concentrated sulphuric acid, to form a sweet smelling ester called ethylethanoate. Its formula is CH3 -COO-CH2-CH3.
The chemical equation for the above reaction is as follows
`C_2 H_5 OH + CH_3 COOH` 
`CH_3 COOC_2 H_5 + H_2 O`
