Solid State
In solids, atoms or molecules are closely packed and the intermolecular space or void is minimum. The average distance between particles is of the order 10 -8 cm; consequently, solids are almost incompressible. In addition, the intermolecular attraction in solids is quite high and for that reason t..
Bonding in Co-ordination Compounds
Bonding in Co-ordination Compounds - The first theory was called the Werner's theory of co-ordination compounds. 1) Metals possess two types of valencies: a) Primary valency or ionizable valency. It is also referred to oxidation state. b) Secondary valency which a metal atom or ..

Bond Energy or Bond Enthalpy - In chemical reactions the formation of a chemical bond is accompanied by the release of energy. Conversely energy has to be supplied for the breaking of a bond. Bond strengths are commonly described by their bondh..
Physical state of the reactants and the products
The D H of a reaction depends upon the physical states of reactants and products. For example, when hydrogen and oxygen gases combine to give liquid water, the heat of reaction is different than when they combine to form gaseous wate..
Hybridization states of carbon atom
The carbon atom of the C-X bond in haloalkanes, is sp 3 hybridised while in haloarenes the carbon atom is sp 2 hybridized. The sp 2 hybridized carbon atom with a greater 's' character is more electronegative. It can hold the electron pair of the bond more..

Physical States of Water
Water is the only substance that can exist simultaneously in all the three states of matter, i.e., solid, liquid and gaseous on this earth,. A simple experiment shows the existence of all these three states together. Take a glass half packed with ice cubes and cover it..

In the case of bonding molecular orbital, the attraction of both the nuclei for both the electrons is increased. This results in lowering of energy. In the case of antibonding molecular orbital, the electrons try to go away from the nuclei and this corresponds to repulsive state..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
This tutors rocked out loud. They were THE BEST tutors. They teaches you everything and explains how to do it and why to do it,awesome tutoring!!!-Ariana
Good teaching skills, an amazing tutoring, would recommend it to everyone - Maadai
The tutors have a wonderful attitude for teaching math. They also wants you to be able to understand all of the concepts. They is better than my regular instructor in my school. TutorVista is the best! - Cody
