Question

A sweet smelling compound a with molecular formula C4H8O2 on hydROLYSIS WITH DILUTE SULFURIC ACID GIVES TWO COMPOUNDS B AND C. B ON OXIDATION WITH K2CR2O7 /H2SO4 GIVES C . IDENTIFY A B AND C .

Answer 1

A is ester, they are sweet smelling compound.

On hydrolysis, B is formed, B is Ethanol ( CH3CH2OH)
C is acetic acid or ethanoic acid (CH3COOH).

Answer 2

Identification of compounds 'A', 'B' and 'C'

Given:

• Molecular formula of compound A = $C_4H_8O_2$
• Compound 'A' on hydrolysis yields 'B' and 'C'.
• Compound 'B' on oxidation with $K_2Cr_2O_7/H_2SO_4$ gives 'C'.

To find:

Compounds 'A', 'B' and 'C' = ?

Explanation:

• From the given molecular formula the compound 'A' is identified as ethyl ethanoate.

• When ethyl ethonate is hydrolyzed with dilute sulfuric acid, it leads to the formation of two compounds namely ethanol and ethanoic acid.

• The chemical equation involved in the reaction is as follows:

$\mathrm{CH}_{3} \mathrm{COOC}_{2} \mathrm{H}_{5}+\mathrm{H}_{2} \mathrm{O} \stackrel{\mathrm{H}_{2} \mathrm{SO}_{4}}{\longrightarrow} \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{CH}_{3} \mathrm{COOH}$

• When ethanol is oxidized with $K_2Cr_2O_7/H_2SO_4,$ it gives ethanoic acid.
• The chemical equation involved in the reaction is as follows:

$C_{2} H_{5} O H+2(O) \stackrel{H_{2} S O_{4}}{\longrightarrow} C H_{3} C O O H+H_{2} O.$

Conclusion:

• From the above-given chemical equations compounds A', 'B' and 'C' are identified as follows:

1. Compound A: Ethyl ethonate - $C_4H_8O_2$
2. Compound B: Ethanol - $C_2H_5OH$
3. Compound C: Ethanoic acid - $CH_3COOH$
