Stereo selective: The reaction is considered as stereo selective if it gives rise to only specific stereo isomer.
Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.
In addition reaction of alkenes when two substituents are placed on same side of
Electrophile: Electrophiles are electron deficient compounds which accepts electrons from nucleophiles that results in bond formation.
Geometric isomers: Two compounds are considered as geometric isomers of each other if both contains same number of atoms but different in their arrangement that is compound is regarded as cis if identical substituents are placed on same side and trans if they are placed on the opposite sides.
E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the bond.
Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the bond.
Erythro product: It is the representation of carbohydrates in Fischer projection when two same substituents are placed on the same side.
Threo product: It is the representation of carbohydrates in Fischer projection when two same substituents are placed on opposite side.
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.
