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.
A drinks can, a pencil lead, a diamond, a window pane and the eyewash in a first-aid box are made of the elements of two neighbouring groups of the periodic table. We follow the boron family and the carbon family: their trends, why boron and carbon behave differently from their neighbours, and the structures and reactions of borax, boric acid, diborane, aluminium compounds, the oxides of carbon, silicates and silicones. The chapter serves the Indian syllabus (NCERT, NEET, JEE Main) and the matching topics of A-Level, IB and AP Chemistry. Python tables the data, counts the bonds of a fullerene and builds silicate formulae.
