Is methanol a ketone

WitrynaAldehydes and ketones react with primary amines to form a class of compounds called imines. The mechanism for imine formation proceeds through the following steps: 1. An unshared pair of electrons on the nitrogen of the amine is attracted to the partial‐positive carbon of the carbonyl group. 2. WitrynaLike compounds methanol, ethanol cannot be oxidized to ketone because they have less than two carbon atoms. For a ketone, at least three carbon atoms are required. So, when an primary alcohol has three or more carbon atoms, there is possibility to produce a ketone by several steps (reactions). which type of alcohol is most easily oxidized?
