Functional Groups

Functional Group

Group of atoms in a molecule that has a characteristic chemical behavior. The chemistry of the molecule is determined by the functional group(s).

• Each __________ has its own chemical and physical properties (structure determines function)

• Written in order of how they are connected along the backbone of the organic molecule

Alkene

Structure: Double carbon bond; 120 degree bond angles; sp2

Intermolecular Forces: Dispersion forces

Alkyne

Structure: Triple carbon bond; 180 degree bond angles; sp

Intermolecular forces: London dispersion forces

Arene/phenyl (aromatic ring)

Structure: 6 carbon atomsbonded; R (carbon based group) is bonded to a carbon

Intermolecular Forces: London dispersion forces
