Coordination Position Isomerism: If in a multinuclear complex the distribution of ligands around the metal centres changes it will result in a different isomer. Such an isomerism
Hofmann Method - Determination of Molecular Mass The method is applied to those substances that are not stable at their boiling points, but that may be volatilised with no deco
Explain term 'depletion layer' across a p-n junction Rectifying action of p-n diode can be explained on the foundation of electronic structure of the semiconductor. When a pure
