Analysis of Organic Compounds

Analysis of Organic Compounds is a practical approach towards accurate identification of formula of a compound, percentage composition of the elements present in it and the functional group(s). It involves 3 important techniques. The first one is the use of chemical tests to identify the functional groups. The second aspect is the use of high ...

Structures & reactions of organic compounds

Compounds which incorporate carbon-carbon bonds or covalent bonds of carbon with other elements like hydrogen, nitrogen, oxygen, sulfur, phosphorous and halogens, are generally classified as organic compounds. The chemical properties of organic compounds are intricately related to their structures. Hence, the classification of organic compounds according to their structures, is an essential part of understanding ...

Measurement In Chemical Analysis

Measurement is involved in every aspect of experimental chemistry and the most important part of this includes the understanding of the skill of the observer and the scope of measurement of a given instrument. To identify any measurement as meaningful, we need to identify some kind of standard against which the measurement is made. Apart ...

Techniques of Volumetric Analysis

Volumetric analysis is a practical approach towards accurate measurement of concentration, molecular mass, purity percentage, formula of compounds, percentage composition of an element and stoichiometry of a chemical equation. It involves 3 important techniques. The first one is the use of apparatus like burette, pipette and volumetric flasks. These are specially made to offer the ...

Shapes of Molecules and Ions

A crucial factor in understanding the chemical reactions is the knowledge of the molecular structure of the various chemical species. The geometry of the molecules decides the fate of a reaction to a large extent. Although defining the structure of a large molecule according to any fixed geometric shape is not practical, the same can ...
