Agenda Collect Alkene activity and ws #2 Quiz on Alkene/ynes Get into Functional Group notes!!! MAYHAN
3
Substituted Hydrocarbons MAYHAN
4
Functional Groups What are functional groups? Functional groups are atoms or groups of atoms that impart specific properties to organic molecules. MAYHAN
5
What is R and R’ ? R and R’ represents a hydrocarbon part of the molecule. CH 3 CH 2 CH 2 CH 2 -OH R CH 3 CH 2 -O-CH 2 CH 3 R R’ MAYHAN
6
Substitution reaction. Substitution reaction is when one atom or groups of atoms in a molecule are replaced by another.
