Identify the Swarts reaction from the following:
Identify the Swarts reaction from the following:
Show Hint
Swarts reaction is useful for converting alkyl halides to alkyl fluorides using metal fluorides like CoF\(_2\) or AgF.
Updated On: May 18, 2025
- \( R-CH_2-Br + NaI \rightarrow R-CH_2-I + NaBr \)
- \( 2R-CH_2-Br + 2Na \rightarrow R-(CH_2)_2-R + 2NaBr \)
- \( 2C_6H_5Cl + 2Na \rightarrow C_6H_5-C_6H_5 + 2NaCl \)
- \( 2R-CH_2-Br + CoF_2 \rightarrow 2R-CH_2-F + CoBr_2 \)

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding Swarts Reaction Swarts reaction is used to prepare alkyl fluorides by reacting alkyl bromides or chlorides with metal fluorides such as CoF\(_2\), Hg\(_2\)F\(_2\), or AgF.
Step 2: Identifying the Correct Reaction - Among the given reactions, only option (4) involves the replacement of Br with F using CoF\(_2\), which follows the Swarts reaction.

- Carbohydrates are polyhydroxy aldehydes or ketones that represent enormous structural diversity in terms of the arrangement of atoms in space, resulting in hundreds of stereoisomers. Although the chemical properties of most stereoisomers may not be very different, their metabolic rate and utilization in biological systems is significantly different and known to influence the overall carbohydrate metabolism. Structural variants, which arise due to a different arrangement of atoms in three-dimensional space are known as stereoisomers. The number of stereoisomers can be theoretically estimated by using the formula 2n, where ‘n’ is the number of stereocenters or asymmetric (chiral) carbon atoms in a molecule. Out of these stereoisomers, there are some structures, which are mirror images of each other, and they are referred to as enantiomers.
