Question

The most suitable reagent for epoxidation is : (a) H5I06
(b) C6H5CO3H
(c) CF3CO3H
(d) OsO4​

Answer 1

Suitable reagent for epoxidation:

Explanation:

• Epoxidation is the chemical reaction that converts the carbon-carbon double bond into oxiranes (epoxides), using a variety of reagents including air oxidation, hypochlorous acid, hydrogen peroxide, and organic peracid.
• It is used as a fumigant and used to make antifreeze, ethylene glycol, and other useful compounds.
• More complex epoxides are commonly made by the epoxidation of alkenes, often using a peroxy-acid (RCO3H) to transfer an oxygen atom.
• A peroxy acid is an acid that contains an acidic –OOH group.
• They are generally strong oxidizers.
• From the above observations, the CF3CO3H ( Trifluoroperacetic acid ) is the strong reagent of epoxidation.

Correct option is: (c) CF3CO3H
