Question

Identify the end product (C) in the following sequence C2H5OH+SOCl2----A+KCN(alc)----B+H2O/H+------C​

Answer 1

Answer:

C2H5Cl-A

C2H5CN-B

C2H5COOH-C

Answer 2

A:C₂H₅Cl

B:C₂H₅CN

C:C₂H₅COOH

Reaction of alcohol with SOCl₂ is called as Darzen's reaction and it is the best reaction to produce halides as the byproducts are gaseous and escapes out easily leaving behind the halide.

C₂H₅OH + SOCl₂ → C₂H₅Cl

C₂H₅Cl + KCN → C₂H₅CN

C₂H₅CN + H₂O/H → C₂H₅COOH
