How do organic reactions actually happen?
Most reactions take place via two or three steps with short-lived, unstable, intermediate ions bridging the steps from reactants to

Alkenes cannot rotate through their C=C double bond, it locks the structure of the molecule in place at that point.

The chemistry that underlies the depletion of ozone in the stratosphere by chlorofluorocarbon molecules is really interesting – an application
Catalysts are able to lower the activation enthalpy, Ea, for a reaction, increasing the number of successful collisions between reactants

Photochemical smog is a brownish haze caused by the action of the sun’s visible and ultraviolet radiation on the primary
Global warming and the greenhouse effect are topics that everyone feels they know well enough (because you’ve done them to
Alkanes are exceptionally boring and unreactive molecules chemically speaking but we can persuade them to react with halogens in the
Petrol needs to be blended to have the right properties in terms of its volatility and to reduce its propensity
Crude oil is the raw material from which alkanes are extracted via the process of fractional distillation. There is nothing
Structural isomers are molecules with the same molecular formula but a different arrangement of atoms … you need to recognise
