They can contain single bonds, triple bonds, and triple bonds.
The can have on the hydrocarbon chain functional groups that contain heteroatoms such as
But, as long as they contain no aromatic rings, they are aliphatic compounds.
Cyclohexanes satisfy the above criteria, so cyclohexanes are aliphatic compounds.
