Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Electrophilic Substitution Reaction | Electrophilic substitution reactions are chemical reactions in which an electrophile displaces a functional group in a compound, which is typically, but not always, a hydrogen atom. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| hydriodic acid | Hydrogen iodide (HI) is a diatomic molecule. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. |

| Dimethyl ether | Dimethyl ether (DME), also known as methoxymethane, is the organic compound with the formula CH 3OCH 3. The simplest ether, it is a colourless gas that is a useful precursor to other organic compounds and an aerosol propellant. |
What you learn in Theory:
Electrophilic aromatic substitution reactions are characteristic of aromatic compounds, and are important ways of introducing functional groups onto benzene rings.
What you learn in Practice:
In electrophilic substitution in aliphatic compounds, an electrophile displaces a functional group. This reaction is similar to nucleophilic aliphatic substitution where the reactant is a nucleophile rather than an electrophile.
