Concept introduction:
Addition of hydrogen halides:
In the addition of hydrogen halides over
Carbocation: carbon ion that bears a positive charge on it.
Carbocation stability order:
Stereoisomers: Two compounds with same molecular formula but different in their orientation are considered as isomers.
The presence of atom with non-super impossible mirror image is defined as enantiomers which are given
R and S nomenclature: it is used to assign the molecule using CIP rules.
The CIP rules are as follows:
Select the chiral carbon and assign the numbers according to the decreasing
If the numbering follows clockwise direction then the molecule is termed as R and if it follows anti-clockwise direction then molecule is termed as S.
Chiral or Asymmetric carbon: Carbon bonded with four different substituents with it is termed as chiral or asymmetric carbon.

Catalytic hydrogenation in presence of
For cyclic reactants, the addition of
(c)
Interpretation:
The product formed when cis- and
Concept introduction:
Acid Catalyzed addition of water: When water is added to alkene in the presence of an acid, the product formed will be an alcohol.
The electrophile
Nucleophile: It donates pair of electrons to positively charged chemical substrate resulting in the formation of
Electrophile: It is positively charged species which seeks for negative charge and hence accepts pair of electrons from negatively charged species (Nucleophiles) which results in the formation of chemical bond.
