How to use this simulation

Play the mechanism or step through it.
Watch the π electrons attack H⁺, then Br⁻ add to the carbocation.
Look at which carbon gets the Br.

What to notice

H adds to the carbon that already has more H atoms.
This gives the more stable carbocation.

Try this

Predict the product of HBr with propene before playing it.
