Conformational isomers or rotamers are infinite numbers of momentary arrangements of groups or atoms in space that results due to the rotation about a single bond. Factors affecting conformational stability of a molecule...

In stereospecific reactions, one stereoisomer of the product is obtained if one stereoisomer of the reactant is present, while different stereoisomers of product are obtained when different stereoisomer of the reactant are...
Isomers resulting from different arrangements of the atoms in space due to the rotation of groups around C-C bond axis are known as conformational isomers. The study of these confirmations or conformational isomers is known as...
Following nomenclature system are used for naming of geometrical isomers: cis and trans nomenclature, E and Z nomenclature, and Syn and Anti nomenclature. cis and trans Nomenclature In a molecule having a carbon-carbon double...
The optically active compounds exist in two or more isomeric form and they differ in their optical activity. The isomers which have same chemical reactions and almost same physical properties but differ in their behaviour towards...
Photolytic degradation is the degradation of photodegradable molecules caused by the absorption of photons, particularly those wavelengths found in sunlight, such as infrared radiation, visible light, and ultraviolet light. Some...
In pharmacy, micromeritics is employed for: Release and Dissolution: Clinically, the particle size and surface area of a drug can affect its release from dosage forms administered orally, parenterally, rectally, and topically...
Figure shows a schematic diagram of Coulter counter equipment used for determining the particle volume. The equipment is applicable to materials of particle size ranging between 0.5-1000μm. Principle The principle involved in...
Emulsions are estimated for their flow behaviour. The flow related attributes desirable for the performance of an emulsion are: Removal of an emulsion from a bottle or tube. Flow of an emulsion through a hypodermic...
Stable emulsions can be produced by using emulsifying agents. These agents reduce the interfacial tension between the two phases and then separate the globules by creating a barrier at the interface. Surfactants are mainly used...
