A2 Unit 4.2 Aromaticity

What does the structure of 1-chlorocyclohexane look like?

What are Alkanes, Alkenes & Alkynes?

Alkane - Hydrocarbon with only single bonds e.g Pentane

Alkene - Hydrocarbon with a double bond e.g Pentene

Alkyne - Hydrocarbon with a triple bond e.g Pentyne

What is an Arene?

Arenes are a type of hydrocarbon.

Arene - Any organic compound with a benzene ring attached (Aromatic) e.g 3-phenyl pentane

What is an Aliphatic hydrocarbon?

Aliphatic - Any organic compound without a benzene ring attached to it, but could be cyclic e.g hexane, cyclohexane, hexene or cyclohexene (straight chain)

What is an Aryl?

Aryl - An adjective used to describe an organic compound with a functional group attached directly to a benzene ring e.g Aryl chloride

What is an Alkyl?

Alkyl - An adjective used to describe a functional group not directly joined to a benzene ring e.g 1-chloro-2-phenyl ethane

Benzene side chain = Phenyl
