Explain Clemmensen reduction with an example.

Explanation

Aldehydes and ketones are heated with zinc amalgam and conc. HCl, to form corresponding hydrocarbons.
`R-overset(O)overset(||)C-R.+4[H\] underset("heat")overset((Zn//Hg+"con.HCl"))toRCH_(2^(-))R.+H_(2)O`
Example: `C_(6)H_(5)COCH_(3)+4[H] underset((Zn//Hg+"con.HCl")) overset("heat")to underset("ethyl benzene")(C_(6)H_(5)CH_(2)CH_(3))+H_(2)O`
