How are aldehydes and ketones prepared from fatty acids?
From fatty acids
Aldehydes are obtained by heating calcium salt of fatty acids with calcium formate.
Ketones are formed by distilling calcium salt of fatty acid alone.
In this method, formic acid alone gives formaldehyde.
Acetic acid gives acetone & the mixture of two acids gives acetaldehyde.How do you prepare alcohol from aldehydes and ketones?
Aldehydes and ketones can undergo reduction process for the formation of either primary alcohol or secondary alcohol with the help of reagents, sodium borohydride (NaBH4) or lithium aluminium hydride (LiAlH4).
Aldehydes and ketones can also form alcohol by the process of catalytic hydrogenation.The Tollens' test is a reaction that is used to distinguish aldehydes from ketones, as aldehydes are able to be oxidized into a carboxylic acid while ketones cannot.
Tollens' reagent, which is a mixture of silver nitrate and ammonia, oxidizes the aldehyde to a carboxylic acid.
What is the method of preparation of aldehydes and ketones?
Aldehyde and Ketone preparation is possible by oxidation of primary and secondary alcohol by agents such as PCC (pyridinium chlorochromate), Collins reagents (Chromium trioxide-pyridine complex), and Cu at 573 K.
