PDF	Chemical tests to distinguish carbonyl compounds 1: Detecting an aldehyde or ketone Aldehydes and ketones react with 24-dinitrophenylhydrazine (24-DNP or 24-DNPH) to form an orange or yellow precipitate

PDF	INORGANICCOMPOUNDS Test given by both aldehydes and ketones 24-Dinitrophenylhydrazine test (24-DNP test) Take 2-3 drops of the liquid compound in a test tube or in case of

The Silver Mirror Test, or Tollen's Test
The silver mirror test is a method used to determine the functional groups present in organic compounds.
It involves combining silver nitrate solution with diluted NaOH to form a brownish deposit.
This can be dissolved by adding a weak ammonia solution._{23 nov. 2023}

What is the 2 4 Dnph test for aldehydes and ketones?

The 2,4-DNP test is a tried and true method for the presence of aldehyde and ketone functional groups in unknown organic compounds.
When an aldehyde or a ketone is placed in a 2,4-DNP solution, a bright yellow-orange or red solid results, which constitutes a positive test.

What is the test for alcohols?

Test for an alcohol: potassium dichromate
1.
To determine between alcohols, add acidified potassium dichromate to the solution. 2.
Primary and secondary alcohols will reduced from orange dichromate(VI) ions to green chromium(III) ions.

What is the test for ketones and aldehydes?

Tollens Test
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.

2,4-Dinitrophenylhydrazine: Aldehydes and ketones react with 2,4-dinitrophenylhydrazine reagent to form yellow, orange, or reddish-orange precipitates, whereas alcohols do not react. Formation of a precipitate therefore indicates the presence of an aldehyde or ketone.
