effective group dynamics

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In th..

Electromeric Effect - This is a temporary effect and takes place between two atoms joined by a multiple bond, i.e., a double or triple bond. It occurs at the requirements of the attacking reagent, and involves instantaneous transfer of a shared pair of electrons of the multiple ..

This is a temporary effect and takes place between two atoms joined by a multiple bond, i.e., a double or triple bond. It occurs at the requirements of the attacking reagent, and involves instantaneous transfer of a shared pair of electrons of the multiple bond to one of the linked atoms...

The atomic radii of elements increases from top to bottom in a group because the nuclear charge increases with increasing atomic number. Although, there is an increase in the principal quantum number from one atom to another, the number of electrons in the valence shell remain the same. ..

In the mechanism of nucleophilic addition, the first step involving the formation of the tetrahedral intermediate, is accelerated by electron withdrawing groups and retarded by electron donating groups. In ketones, the carbonyl carbon is attached to two alkyl groups, ..

. Just prior to rainfall especially in early kharif days, the climate is warm and dusty because of thick cloudy cover in air not allowing the earth's reflected radiation to pass through. The air gets heated up due to absorption of long range waves from both direct and reflected source. This phenome..

Steric effect refers to the crowding of alkyl groups around N atom which hinders the attack of proton on the amine molecule and this decreases its basic strength. Since crowding of alkyl groups around N atom increases from 1 o to 3 o amines, the basic strength of am..

Association The weak electrostatic interactions of intermolecular hydrogen bonding, causes two or more molecules of a compound to exist as aggregates or associated molecules. This is seen in water molecules, which undergo molecular association. Alcohols and carboxylic acids (RCOOH) als..

. Methanol has a dipole moment of 1.71 D whereas phenol has a dipole moment of 1.54 D. The smaller dipole moment of phenol is due to the electron withdrawing effect of phenyl group in contrast to the electron releasing effect of alkyl group in alcohols. In et..
