Notes On Gaseous State This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules. 2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas. 3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel. 4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions. 5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r
Notes on GE Chemistry - II (Generic Elective Chemistry - II) Aromatic Hydrocarbons: Compounds having chemistry similar to benzene are traditionally known as aromatic compounds. Benzene shows some unexpected chemical behaviour and a remarkable stability despite the presence of high degree of unsaturation. This special characteristic which imparts stability to the aromatic compounds is called the aromaticity. Aromaticity is a property of typical cyclic planar molecular structures which are generally more stable compared to similar geometric or connective arrangements with the same set of atoms due to pi bonds in resonanance (or delocalisation of electrons). Conditions of aromaticity: The compounds or species are considered to be aromatic if they fulfill the following conditions: 1. The cyclic compounds must have conjugated double bonds. 2. Each ring atom should have an unhybridised p orbital to result in sp2 hybidisation. These unhybridised p orbitals must overlap to form a
