Question

1.A Compound (A) with molecular formula C2H3N on acid hydrolysis gives(B) which reacts with thionylchloride to give compound(C). Benzene reacts with compound (C) inpresence of anhydrous AlCl3 to give compound(D). Compound (D) on reduction with Zn/Hg and Conc.HCl gives (E). Identify (A), (B), (C), (D) and (E). Write the equations.​

Answer 1

Explanation:

A) Methyl cyanide (CH₃CN) is the compound that has C₂H₃N molecular formula.

B) When methyl cyanide reacts with acid and water it gives acetic acid.

CH₃CN + H⁺/H₂O → CH₃COOH

C) When acetic acid reacts with thionyl chloride, it gives acetyl chloride.

CH₃COOH + SOCl₂ → CH₃COCl

D) Acetyl chloride reacts with benzene in presence of anhyd. AlCl₃ and gives acetophenone.

CH₃COCl + C₆H₆ + anhy. AlCl₃ → C₆H₅COCH₃

E) Acetophenone on reduction gives ethylbenzene.

    C₆H₅COCH₃ + Zn/Hg → C₆H₅CH₂CH₃
