FUNDAMENTAL PARTICLES OF AN ATOM
The word atom has been derived from the greek word atomos means indivisible. But now it has
been discovered that atom is not the smallest particle in the universe. Rather it is still made up of

Compounds having the same structural formula but different spatial arrangement of atoms or groups are
called stereoisomers and the phenomenon is called stereoisomerism.
Types of stereoisomerism: It is of the following three types.
1. 3 basic kinds of reactions similar to those from Chem 1 but called something else
a. Addition Reactions (like synthesis reactions)
1. saturating an unsaturated carbon chain
2. alkene/yne to alkane
COLLISION THEORY OF REACTION RATES:
For a reaction to take place, it is necessary for the molecules to collide among themselves
. But all the collisions are not effective. Therefore apart from collision alone to form product
molecules, other factors are a
