Question #109622

How is an aldehyde produced? And what is the oxidation product of an aldehyde?

Expert's answer

Generally aldehydes produced by oxidation (using wide range of reagents) of primary alcohols (secondary alcohols oxidized to ketones)

Primary: results in aldehyde

Secondary: results in ketone


Reagents suitable for oxidation of primary alcohols:

  • CrO3/t-BuOH
  • Na2Cr2O7/H2SO4
  • MnO2/C5H12
  • CrO3*2Py
  • etc.

Some of reagents can further oxidize appearing aldehyde to caboxylic acid, so you must use selective reagents (that modify only primary alcohol group -CH2-OH or carefully count stoichiometry).

Further oxidation of aldehydes lead to carboxylic acid formation:
