Question

What is hunsdiecker reaction? Is this reaction available in ncert book?

Answer 1

The Hunsdiecker reaction (also called the Borodin reaction or the Hunsdiecker–Borodin reaction) is a name reaction in organic chemistry whereby silver salts of carboxylic acids react with a halogen to produce an organic halide.[1] It is an example of both a decarboxylation and a halogenation reaction as the product has one fewer carbon atoms than the starting material (lost as carbon dioxide) and a halogen atom is introduced its place. The reaction was first demonstrated by Alexander Borodin in his 1861 reports of the preparation of methyl bromide from silver acetate.

Answer 2

Hey !

              HUNSDIECKER'S REACTION

Bromoalkanes are obtained by this method by refluxing silver salts of fatty acids with Br₂ in CCl₄

  R ------COOAh + Br₂ --(CCl₄)--> R ---- Br + AgBr + CO₂

  CH₃CH₂COOAg + Br₂ --(CCl₄)--> CH₃CH₂BR + AgBr + CO₂

This method can be employed to decrease the number of carbon atoms.

Good luck !!
