IUPAC Nomenclature - Chemistry Short Handwritten Notes [PDF]📚

IUPAC nomenclature, developed by the International Union of Pure and Applied Chemistry, is a systematic method for naming chemical compounds. It ensures clarity and consistency in communication across different languages and disciplines. Here's a quick overview:

IUPAC Nomenclature - Key Principles

Unique and unambiguous: Each name corresponds to a single structure, and vice versa.

Based on parent chain: The longest continuous chain of carbon atoms forms the base name.

Functional groups: Different functional groups have specific suffixes attached to the base name.

Substituents: Other atoms or groups attached to the chain are named as prefixes.

Priorities: Functional groups and substituents have priorities to determine their order in the name.

IUPAC Nomenclature - Steps for Naming

Identify the parent chain: Choose the longest continuous chain of carbon atoms.

Number the chain: Start numbering from the end closest to a functional group (if present).

Identify functional groups: Assign suffixes based on priority (e.g., -ol for alcohol, -one for ketone).

Identify substituents: Name and number them based on their position on the chain (e.g., chloro-, 2-methyl-).

Assemble the name: Combine prefixes, numbers, and suffixes in the correct order.
