Lecture Note: https://drive.google.com/file/d/1YbTf... 🎓 Welcome to EduNex Nepal – Your Learning Partner for Class 10, 11 & 12 Empowering NEB students with quality education, concept clarity, and complete exam preparation support. This chapter covers three important organic compounds containing oxygen: alcohols, phenols, and ethers. It explains their structure, classification, nomenclature, and preparation methods. You will learn about the physical and chemical properties of these compounds, including reactions like oxidation, dehydration, and substitution. Special focus is given to the acidity of phenols, hydrogen bonding in alcohols, and the unique behavior of ethers. The chapter also highlights real-life applications of these compounds in medicine, industry, and daily life. Understanding this chapter builds a strong foundation in organic chemistry and helps in solving both theoretical and numerical questions for NEB board exams. Chemistry is one of the most important subjects for NEB Class 12 Science students, but many students feel confused while preparing for it. The truth is — Chemistry becomes much easier when you understand the concepts clearly and practice the right types of questions regularly. Chemistry is not only about memorizing reactions and formulas; it is about understanding concepts, mechanisms, and applying them correctly in exams. In this video, we will explain the best strategy to study Chemistry for the NEB Board Exam 2083, along with the most common mistakes students make while preparing for chemistry. Many students lose marks in chemistry not because the subject is difficult, but because they follow the wrong study approach. This video will guide you on how toppers prepare for chemistry, how to remember reactions effectively, how to practice numericals and theory questions, and how to manage time during the NEB chemistry exam. In this video you will learn: • How to study Chemistry effectively for NEB Class 12 • Smart techniques to remember reactions, formulas, and mechanisms • The correct way to practice Physical, Organic, and Inorganic Chemistry • How to revise important concepts, reactions, and derivations efficiently • Common mistakes students make in the Chemistry exam • How to improve your answer writing for board exams If you are preparing for the NEB Board Exam 2083, this video will help you build a clear and practical strategy to improve your chemistry score. Chemistry becomes easier when you understand the concepts clearly, practice numericals and reactions regularly, and revise important topics consistently. Watch this video till the end to learn the best chemistry study techniques used by high-scoring students. 🎓 This video is specially made for NEB Class 12 Science students preparing for Chemistry Board Exams. 00:00:00 Intro 00:00:27 Overview: NEB Exam Strategy & Important Questions 00:01:25 Basic Terms: System, Surroundings, and Boundary 00:10:45 Types of Systems (Open, Closed, and Isolated) 00:25:30 Intensive vs. Extensive Properties 00:45:00 State Functions vs. Path Functions 01:15:20 First Law of Thermodynamics 01:45:10 Internal Energy and Enthalpy 02:15:30 Heat Capacity at Constant Volume and Pressure 02:50:00 Hess’s Law of Constant Heat Summation 03:15:45 Introduction to Entropy and the Second Law 03:30:00 Gibbs Free Energy and Spontaneity 03:38:28 Mathematical Derivation: Relationship between ΔG, ΔH, and ΔS 03:39:07 Useful Work and the Significance of Free Energy Change 03:39:23 Closing Remarks & Next Class Announcement #NEBClass12 #ChemistryClass12 #NEBChemistry #Class12Chemistry #NEB2083 #EduNexNepal #chemistryexampreparation #chemistry2083
