Question

What is swartz reaction

Answer 1

Swartz reaction is a reaction in which alkyl fluorides are formed when alkyl bromide or chloride reacts with metal fluorides.

Answer 2

Answer:

Swarts' reaction is generally used to get alkyl fluorides from alkyl chlorides or alkyl bromides. This is done by heating of the alkyl chloride/bromide in the presence of the fluoride of some heavy metals.

Explanation:

The chemical equations of Swarts reaction:

Alkyl chlorides (or bromides) are heated in presence of metallic fluorides such as

AgF,CoF 2 ,SbF 3 ,Hg 2F

2 .CH3 −Cl+AgF→CH3 −F+AgCl

1. Swarts reaction is a simple nucleophilic substitution reaction.

2. The mixture of antimony trifluoride and chlorine (SbF3+Cl2) is known as Swarts reagent.

3. Generally, alkyl fluorides can be prepared by Swarts reaction. This is a simple halogen exchange method.

4. Halogen of smaller atomic size replaced by halogen of greater atomic size.

Atomic size of Halogen are I>Br>Cl>F.
