Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Petrol, cooking gas, plastic bags and the benzene ring in a dye all come from compounds of carbon and hydrogen only. These hydrocarbons are the parent family of organic chemistry. In this chapter you learn how alkanes, alkenes, alkynes and benzene are made, how their shapes and bonds decide what they do, and why a double bond adds a reagent where a ring of six carbon atoms prefers to keep its stability. It serves the Indian syllabus (NCERT, NEET, JEE Main) and the matching topics of A-Level, IB and AP Chemistry. Python counts isomers and works out product mixtures.
