In ether analysis, ethers, like hydrocarbons, are not very reactive but can be distinguished from ethers by the iodinecharge transfer test and by solubility in H2SO4 (not diaryl ethers). When ethers are left to stand exposed to air and light they have a tendency to form highly explosive peroxides. Ferrox paper test Procedure: this paper … Read more
Carbohydrate analysis focuses on mono– and –disaccharides which are colorless solids or viscous liquids that dissolve readily in water. In the IR spectrum they exhibit strong hydroxyl absorptions and usually no carbonyl absorption. A main feature of carbohydrate analysis is that the “reductant” sugars are oxidized by the Tollens’ reagent and the Fehling reagent (see … Read more
Almost all amides are colorless crystalline solids. In the analysis of amides, the observation of the infrared (IR) spectrum is important. In this spectrum, two bands are observed in the region of the carbonyl group (amide I and II) in addition to the stress band of the N-H group in the region of 3400 cm-1. … Read more
The analysis of aromatic hydrocarbons gives negative results in the tests with bromine in CCl4 and with alkaline permanganate, and they also burn with a characteristic dark flame. Most alkylated aromatic hydrocarbons are liquids, but those with more than one ring (fused or not) are solids. Solubility in H2SO4: Simple aromatic hydrocarbons are insoluble in … Read more
In the analysis of alkyl halides, the presence or absence of halogens in organic compounds can be determined by the Beilstein test, consisting of the formation of copper halides that give the flame a green or blue coloration, or by the analysis of the filtrate obtained after fusion with sodium. In order to classify the … Read more
Common characteristics of aldehydes and ketones Aldehydes and ketones have characteristic reactions in common due to the presence of the carbonyl group in both, but they also have distinct reactions due to the property of aldehydes to be oxidized to acids by the action of mild oxidants. The analysis of aldehydes and ketones focuses on … Read more
On an industrial scale Mainly chlorides, they are generally prepared by direct halogenation of hydrocarbons at high temperatures, by means of free radicals. Although most of the time mixtures containing isomers and varying amounts of halogen are obtained. However, industrially they are useful, since these mixtures can be used as such. Many fluorides, industrially, are … Read more

What are azoles? The azoles are five-membered cyclic organic compounds having one or more non-carbon atoms in the ring, at least one of the heteroatoms being nitrogen. This is the largest and most diverse group of aromatic heterocycles. They are derived from furan, thiophene and pyrrole, by replacement of one or more CH groups by … Read more
What is nucleophilic substitution of pyridines? The nucleophilic substitution reaction is not a common process in benzene chemistry, but it is much easier in pyridines, and particularly at the C2 and C4 positions which are activated by nitrogen. Nucleophilic displacement of a good leaving group, via addition-elimination, occurs most easily for groups at C2 and … Read more
