identification of the three groups of acidic radical.id

Thus carboxylic acids give brisk effervescence with aqueous NaHCO 3 solution. This reaction can be used to detect the presence of carboxyl group in a compound. Also this reaction is used to differentiate between carboxylic acids and phenols which do not give ..

Some Important Carbon Compounds - Ethanoic Acid - Acetic acid is one of the commonest organic acids and has been known for quite a long time in the form of vinegar. It is also present free in a number of fruit juices. In the combined state it occurs in many oils and es..

>COOH. The electronegativity and thus the electron withdrawing power of the halogen substituent and thus the strength of the acid decreases in the given order. CH 3 CCOOH > Cl 2 CHCOOH > ClCH 2 COOH > CH 3 COOH The number of electron withdrawing chloro gr..

. In acidic solution, the carboxylate function (- COO - ) accepts a proton and gets converted to carboxyl substituent (- COOH) while in basic solution the ammonium substituent (+NH 3 ) changes to amino group (-NH 2 ) by losing a proton. In acidic solution, an..

The esterification of carboxylic acids with alcohols is a kind of nucleophilic acyl substitution. The first step is the protonation of the carbonyl oxygen, which activates the carbonyl group towards nucleophilic addition of the alcohol. The tetrahedral intermediate, which is ..

Naming Compounds With More Than One Different Functional Groups - When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent chain is done..

Alcohols, phenols, ethers, aldehydes, ketones and carboxylic acids are compounds with functional groups containing oxygen. An alcohol contains one or more hydroxyl (OH) groups(s) attached to aliphatic carbon atom(s). For e.g., ethyl alcohol formula CH 3..

Summary - Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combined state it is found in water,..

When a molecule contains more than one similar functional groups, then, the word di (for 2), tri (for 3), etc., is added before the secondary suffix, of the functional group. While adding such words, the vowel 'e' of primary suffix is retained. For example: Here, Word ..

Summary - Oxygen and sulphur belong to group VI A. Oxygen shows a valency of -2, while sulphur shows a valency of -2, +4 and +6. Industrially oxygen is manufactured by fractional distillation of liquid air free of dust particles and CO 2 . Oxides of mercury, silver and lead decompose to g..
