molecularity and order

Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular reaction, a single molecule shakes i..

Rules for Filling Molecular Orbitals - The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accord..

In order to explain the observed behaviour of gases, a model was proposed based on the molecular and kinetic concept of gas molecules. This model takes into account the particulate nature of matter and the constant movement of particl..

In order to determine the molecular mass of unknown non volatile compound, a known mass (say w g) of the compound is dissolved to prepare a known volume (say v liters) of solution. The osmotic pressure of the solution is determined and the molar mass is calculated as follows: wh..

The cation is named first (whether simple or complex) then the anion. Example: [Co(NH 3 ) 6 ]Cl 3 hexaammine cobalt (III) chloride. K 2 [PtCl 6 ] potassium hexachloroplatinate (IV). Name is started with a small letter and the complex part is written as one word. For non-ionic or molecular..

Homologous series is a series of organic compounds having the same general formula, arranged in an ascending order of their molecular masses. Each member of the series is called homologu..

Solids are substances having definite volume and definite shape. In terms of kinetic molecular model, in solids there is a regular order in the arrangement of the constituting particles (atoms, molecules or ions) i.e. the particles constituting the solids occupy fixed positions ..

Primarily surface tension of a liquid is governed by the strength of intermolecular attractive forces. Therefore, the magnitude of surface tension is a measure of intermolecular attractive forces. For instance the order of strength between inter molecular forces as well as the ..
