Alkanes, Alkenes & Alkynes Explained | Hydrocarbons Part-2 | Organic Chemistry Basics

Описание: Welcome to NirHix TechLearn 🚀
A dedicated platform for clear, conceptual and exam-oriented Chemistry learning.

In this video, we continue the Hydrocarbons chapter (Part-2) and explain Alkanes, Alkenes, and Alkynes in a detailed, systematic, and concept-building manner. This lecture is designed to strengthen the core foundation of Organic Chemistry after understanding the basics covered in Part-1.

Alkanes, Alkenes, and Alkynes are the fundamental building blocks of Organic Chemistry. A clear understanding of these compounds is essential to learn advanced chapters like Alcohols, Haloalkanes, Polymers, Fuels, Petrochemistry, and Organic Reactions.
