Hydrocarbons — three ways to learn it.

Read the full lecture, watch bromine water decolourise across a C=C and benzene's electrons circulate in the interactive lecture, then test yourself. Pick any door — they all teach the same chapter.

Section 1

📖

Lecture & walkthrough

The complete written lesson — classification of hydrocarbons, alkanes (free-radical halogenation mechanism), alkenes (electrophilic addition & Markovnikov's rule), alkynes, and benzene's aromaticity & electrophilic substitution.

As you scroll, a live D3 panel animates every idea: the free-radical chain reaction, an electrophilic addition where orange bromine water decolourises across a C=C, Markovnikov addition, and benzene's delocalised π electrons circulating around the ring.

Practical experiment

Test a hydrocarbon with bromine water on a 3D bench — watch an alkene decolourise the orange as Br₂ adds across its C=C.
