Ketones and aldehydes are organic compounds which contain a carbonyl group. These carbonic chemical compounds can be made artificially. The main difference between aldehydes and ketones is their chemical structure. Some tests which help them distinct from each other are Schiff’s test, Tollen’s test, Fehling’s test, Sodium hydroxide test, etc. the result is as follows.
|Test Name||Aldehyde – Result||Ketone – Result|
|Schiff’s test||Pink colour||No colour|
|Tollen’s test||Black precipitate||None|
|Fehling’s test||Reddish precipitate||None|
|Sodium hydroxide test||Brownish resinous material||No reaction|
Difference Between Aldehydes And Ketones
|Occur||End of the carbon chain||Middle of the carbon chain|
|Reactivity||More reactive||Less reactive|
