hello sameer saxena...,

the organic chemistry is the very important part for jee examination having the highest waitage in chemistry. The basic organic chemistry reaction types are addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions, photochemical reactions and redox reactions. In organic synthesis, organic reactions are used in the construction of new organic molecules.

The four main types of reactions in organic chemistry are substitution 1 (Sn1), substitution 2 (Sn2), elimination 1 (E1), and elimination 2 (E2).

here are the few topics covered in organic chemistry.

• Structure and bonding. ...
• Resonance and acid-base chemistry. ...
• Alkanes, cycloalkanes, and functional groups. ...
• Stereochemistry. ...
• Substitution and elimination reactions. ...
• Alkenes and alkynes. ...
• Alcohols, ethers, epoxides, sulfides. ...
• Conjugated systems and pericyclic reactions.

hope this information was useful to you....

all the best for your bright future....
