This test is used to distinguish ketones and aldehydes from alcohols and esters, which do not react with DNPH and therefore do not generate a precipitate. The ketone or aldehyde derivatives are crystalline solids with well-defined melting temperatures that have been documented in the literature and ...
Benedict's test is a simple chemistry test used todetect reducing sugars. Reducing sugars are carbohydrates having free aldehyde or ketone functional group in its molecular structure. These include monosaccharides like glucose and fructose and disaccharides like lactose and maltose[1-4]. What is Bened...
Tollens’ test is one of the tests used to distinguish between aldehydes and ketones. This test is mostly given by the compounds containing the aldehyde group. As a silver mirror is produced at the end of the reaction due to the formation of silver metal, it is also called a silver mirror...

2. A method of screening a solution for an analyte that has been dissolved in a solvent to form the solution and for detecting the presence of the analyte when the solution is deposited in a sorbent material so that the analyte is separated from the solvent at the place of application to...
The red colour precipitate confirms the presence of an aldehyde functional group in the sample. Uses of Fehling’s test: Fehling’s test is used for the following purposes: To differentiate between the non – reducing and reducing sugar. To distinguish between the type of carbohydrates present ...
Such difunctional examples are suited to the preparation of many types of polymers and a review of this area has appeared <2002MI1086>. Dialdehyde 303, prepared by the oxidation of the dimethyl precursor, was reacted with diamine 304 to produce the polyimide 305 (Equation 2) <2003MI43>. ...
