Isomerism in Organic Chemistry
Explore the different types of isomerism, including structural isomerism (chain, position, functional, metamerism, tautomerism) and stereoisomerism (geometric and optical isomers).
Why this shows up in the exam
Identifying and distinguishing isomers is a frequent requirement in competitive exams.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
The IUPAC name of the following compound is Cl | CH₃-C=C-CH₂CH₃ | CH₃ | I
Push further
More challenging9 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
