Organic Chemistry Basics (Class 11): IUPAC Naming and Isomerism
Class 11 · Chemistry Organic Chemistry Basics (Class 11): IUPAC Naming and Isomerism Naming is a procedure with a fixed order of steps. Follow the order and long names become routine; guess at it and even short ones go wrong. Class 11 · CBSE & ISC · Concept and method The short answer: Find the longest chain containing the principal functional group, number it so that group gets the lowest locant, name the substituents alphabetically, and assemble. Isomerism then splits into structural — same formula, different connectivity — and stereoisomerism, where connectivity matches but spatial arrangement differs. IUPAC naming, in…
