identification of functional groups in organic compounds

The identification and characterization of an organic compound such as molecular formula etc., must have the compound available in pure form. The process of obtaining the compound in its purest form from an impure sample or from any reaction m..

There is no direct method for the detection of oxygen in organic compounds. It's presence is detected indirectly. For example, If any organic compound on heating in a dry test tube, gives out water vapor, then the presence of oxygen in the organic..

It is quite evident that carbon displays a great propensity in forming a large variety of carbon and hydrogen compounds. But carbon can also form bonds with other elements in a hydrocarbon chain, when one or more hydrogen is replaced by an element like oxygen, nitrogen, sulphur etc. such..

The simplest organic compounds are hydrocarbons. All organic compounds can be derived from hydrocarbons by substituting a hydrogen atom with a suitable functional group. Replacing a hydrogen atom by a OH group in a hydrocar..

There are millions of organic compounds and this makes it physically impossible to study each individual compound. To facilitate their study, organic compounds are classified into various groups and sub-groups..

The identification and characterization of an organic compound such as molecular formula etc., must have the compound available in pure form. The process of obtaining the compound in its purest form from an impure sample or from any reaction mixture..

Dyes - Chromophores - Unsaturated groups or groups with multiple bonds that impart color to the organic compound are called chromophores. Examples are the nitro, the nitroso and the azo groups..

The functional group is an atom, or a group of atoms which can replace one or more hydrogen/s in a hydrocarbon. This group when present in organic compounds defines the characteristic physical and chemical properties of that particular fa..

Many enzymes can exhibit their catalytic activity only when they are in association with some non-protein substance. Such substances are called cofactors. The cofactors may be simple metal ions like Mg + + or complete organic compounds. An enzyme which functions only i..

Organic compounds that contain one or more carboxyl groups, (-COOH) have acidic properties and are known as carboxylic acids . The word carboxyl rightly represents this functional group in the sense that it is a combination of the carbonyl grou..
