Consider the following organic compounds:
HCHO, C2H5OH, C2H6, CH3COOH, C2H5CI
Choose two compounds which can react in the presence of conc. H2SO4 to form an ester. Give the name and formula of the ester formed.
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`
