Chemistry notes class 12

Will you please provide me notes for the chemistry subject of class 12th ??

Here I am giving you notes for the chemistry subject of class 12th in a word file with it so you can get it easily..

CAUSE OF EXISTENCE OF SOME SUBSTANCES AS SOLIDS:-

1. Intermolecular Forces:-
These are the forces existing among the constituent particles of substance which keep them close together.

2. Thermal energy:-
This is the energy possessed by the constituent particles molecules apart as it tends to make them move fast. As low temperature intermolecular forces are strong and thermal energy is low. Thus the constituent particles only oscillate about their mean position and substance exists as solid.

GENERAL CHATERISTICS OF SOLID STATE:-
Solids possess following properties:-
The constituent particles are very closely packed and the intermolecular distances are very small.
The constituent particles occupy fixed positions and they can only oscillate about their mean positions.
They possess rigidity.
They have high density.
They possess definite shape and volume.
They are incompressible.

1. Crystalline Solids:-
A solid is said to be crystalline if its various constituent particles [ions, atoms, molecules] are arranges in a definite geometric pattern in the three dimensional space so that there is short as well as long range order of constituent particles.Example:- Sodium, Calcium, Stones, Gems, Wood etc.

2. Amorphous Solid:-
If there is no regular arrangement of constituent particles or there is only the short range order of its constituent particles then the solid is called amorphous solid.Example:- Rubber, Glass, Pitch, Silica etc.

3. Isotropy:-
In the amorphous solids there is no regular arrangement of particles thus the properties like electrical conductivity, thermal expansion are identical in all the direction. This property is called isotropy.

Amorphous solid are isotropic in nature.

4. Anisotropy:-
Due to regular arrangement of constituent particles, the different particles are fall in different ways of a crystalline solid. The values of properties like electrical conductivity and thermal expansion not remains same in all the direction this is called anisotropy.
