Explain Clemmensen's reduction with an example. - Toppr
Clemmensen reduction is used to reduce aldehydes and ketones to hydrocarbons. Zinc amalgam and concentrated hydrochloric acid are used as Clemmensen's reagent. Clemmensen reduction is a reaction which involves the reduction of a carbonyl compound to form a simple hydrocarbon.
Explain the following with suitable example: (a) Clemmensen …
(a) Clemmensen reduction: Carbonyl compounds (aldehydes and ketones), that are not sensitive to acids, are heated with zinc amalgam and conc HCl to give alkanes. Carbonyl group is reduced to methylene group.
The reagent used in Clemmensen's reduction is: - Toppr
The mechanism for the Clemmensen reduction is not yet fully understood and there are two popular proposals. The "Carbanionic mechanism", where the zinc attacks the protonated carbonyl directly, and the "Carbenoid mechanism", which is a radical process and the reduction happens on the surface of the zinc metal.
Write a short note on clemmensen's reduction. - Toppr
The Clemmensen reduction is a reaction that is used to reduce aldehydes or ketones to alkanes using hydrochloric acid and zinc amalgam. This reaction is particularly effective in aryl-alkyl ketones reduction formed in Friedel-Crafts acylation. The reaction is more effective in reduction of cyclic ketones or aliphatic and zinc metal.
