BSC 3rd sem Important Organic Chemistry Chapters for Prepration

Stereochemistry: This branch of organic chemistry deals with the spatial arrangement of atoms in molecules

Aromatic Compounds: Aromatic compounds are a class of organic molecules characterized by the presence of a benzene ring

Aldehydes and Ketones: These functional groups, characterized by the presence of a carbonyl group (C=O)

Carboxylic Acids and Derivatives: Carboxylic acids are organic molecules containing a carboxyl group (COOH). 

Reaction Mechanisms: Understanding reaction mechanisms is vital for comprehending how organic reactions 

In addition to these core chapters, familiarizing yourself with spectroscopy techniques like NMR,  IR, and Mass spectrometry is also highly recommended.

Remember, a comprehensive understanding requires going beyond memorization and developing a solid grasp of the underlying concepts.
