identification of the three groups of the acidic radicals

The names of acids containing radicals or polyatomic groups are given on the basis of second element, but prefix hydro is not used. Example: H 2 SO 4 is Sulphuric Acid H 2 CO 3 is Carbonic Acid H 2 SO 3 is Sulphurous Acid..

The order of stability of alkyl free radicals is: CH 3 < 1 o < 2 o < 3 o This order of stability can easily be explained on the basis of hyperconjugation. Larger the number of alkyl groups, attached to the carbon atom carrying the odd electron, gre..

The tribasic acids can combine with three hydroxyl groups. These acids must have three replaceable hydrogen ions, and as such they can form three types of salts e.g., phosphoric acid (H 3 PO 4 ). Phosphoric acid dissociates in water in t..

. Both those dipeptides have 3 free functional groups which further react with relevant groups of other amino acids forming tri, tetra, penta peptides and so on. Both -CO and -NH groups of peptide bonds are polar. They are involved in hydrogen bond ..

- ) 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 amino acid exists as a positive ion and migr..

A bisalt or an acid salt contains replaceable hydrogen ions in association with the acidic radicals. It is obtained by the incomplete replacement of hydrogen ions by metal ions or ammonium ions. Examples: NaHCO 3 , NaH 2 PO 4 and Na 2 HPO 4 . Since such s..

> acts as an acid in its reaction with NaOH; and NH 3 acts as a base although it does not contain OH - group. In aqueous solutions, hydrogen ion exist as hydrated species (H 9 O 4 + ) which is described by a simple formula H 3 O..

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 essential oils. Formula: CH 3 COOH, IUPAC Name: Eth..

Summary - Chlorine belongs to group VII A. Members of this group are called halogens which means 'salt producers'. Chlorine is a greenish yellow gas. Chlorine has seven electrons in its outer most shell and so has a valency of 1. Like other halogens chlorine is a strong oxidisin..

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 so that the functional group of higher priority gets the lower nu..
