Question

write equations of clemension's reduction

Answer 1

Clemmensen reduction



The Clemmensen reduction is an organic reaction used to reduce an aldehyde or ketone to an alkane using amalgamated zinc and hydrochloric acid. 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.

Answer 2

Clemmensen reduction is a chemical reactiondescribed as a reduction of ketones (oraldehydes) to alkanes using zinc amalgamand hydrochloric acid.[1][2][3] This reaction is named after Erik Christian Clemmensen, a Danish chemist.[4]
The Clemmensen reduction is particularly effective at reducing aryl-alkyl ketones,[5][6]such as those formed in a Friedel-Crafts acylation. With aliphatic or cyclic ketones,zinc metal reduction is much more effective.[7]

The substrate must be unreactive to the strongly acidic conditions of the Clemmensen reduction. Acid-sensitive substrates should be reacted in the Wolff-Kishner reduction, which utilizes strongly basic conditions; a further, milder method is the Mozingo reduction. The oxygen atom is lost in the form of one molecule of water.
