Top 5 YouTube Lessons on Isomerism for NEET Chemistry by PW

Organic Chemistry: Isomerism requires you to recognise how compounds with the same molecular formula can differ in connectivity or spatial arrangement. Applying the right rules to structural isomers, geometrical configurations, optical activity, and isomer counting can be challenging, especially when a question tests more than one concept.

Physics Wallah’s YouTube videos offer different ways to tackle Isomerism, from revisiting individual concepts to reviewing the full chapter in a single lesson. Compare structural and stereoisomers, practise identifying configurations, and use isomer-counting questions to check your understanding before the NEET Chemistry exam.

Video 1: Revise Every Major Type of Isomerism with One-Shot Concepts, Tricks and PYQs

Need to revise the entire Isomerism chapter without switching between multiple lessons? This one-shot covers the meaning and classification of isomerism, including chain, position, metameric, functional, tautomeric, and ring-chain isomerism. You will also revisit Bredt’s rule, structural-isomer counting, geometrical isomerism, optical isomerism, and conformational isomerism. Previous-year questions give you practice applying these concepts to exam-style problems. Use this lesson to connect the different types of isomerism, recall important rules, and review the chapter before attempting mixed NEET Chemistry questions.

Video 2: Progress from Isomerism Basics to Advanced Concepts 

Still finding it difficult to move from basic isomerism concepts to challenging questions? This Class 11 one-shot begins with the meaning and classification of isomerism, then moves through structural, conformational, and geometrical isomerism. You will learn to distinguish these forms and work through calculations involving geometrical isomers. The progression from introductory concepts to advanced applications, followed by previous-year questions, helps you build understanding and apply the relevant rules. Use this lesson to strengthen your foundation and practise solving NEET Chemistry questions with greater accuracy.

Video 3: Cover Isomerism in 87 Minutes with a Focused Crash Course

Short on revision time but need to revisit the main Isomerism concepts? This 87-minute lesson covers structural isomerism, stereoisomerism, and geometrical isomerism in a focused crash course. The explanations introduce the key ideas before moving towards isomerism-based problem-solving. You can use the lesson to reconnect the major concepts, review the differences between isomer types, and practise applying them to Chemistry questions. Its shorter format makes it useful when you want a chapter recap before a mock test or need to revisit the basics without committing to a longer lecture.

Video 4: Revise the Full Isomerism Chapter in 68 Minutes with Key Rules and Questions

Want a chapter-wide recap that covers both structural and stereoisomerism? This 68-minute lesson starts with the degree of unsaturation and the classification of isomers before covering chain, position, functional, ring-chain, metameric, and tautomeric isomerism. You will also revisit priority order, stereocentres, geometrical isomerism in different compounds, configurations, and related counting questions. The topic-by-topic coverage helps you connect the chapter’s major concepts and practise identifying different isomer types. Use this lesson for a focused revision of important rules and applications before your NEET Chemistry exam.

Video 5: Master Structural, Optical and Geometrical Isomerism in One Shot

Need to connect structure, symmetry, and isomer counting instead of memorising each type separately? This one-shot covers chain, position, functional group, metameric, and ring-chain isomerism, along with structural-isomer counting. It then moves to geometrical nomenclature, structure representation, optical isomerism, symmetry, optical-isomer counting, and conformational isomerism. Previous-year questions help you apply these concepts and check your understanding. Use this lesson when you need detailed chapter preparation, especially for questions involving naming, spatial arrangement, symmetry, and the number of possible isomers.

As you revise Isomerism for NEET, focus on recognising the differences between isomers and understanding how each type is identified. Use PW’s YouTube videos to revisit challenging areas, work through questions on isomer counting and configurations, and check your progress with previous-year questions. Regular practice will help you approach this chapter’s varied question types with greater clarity and accuracy.
