Alkenes and Alkynes Learning objectives: 1. Describe the three-dimensional structure of an alkene and reason the structure with the overlapping of hybridized and non-hybridized atomic orbitals of carbons. 2. Name alkenes including cis-trans and/or E-Z assignments when necessary. 3. Name alkynes. 4. Show the terpene units that can be fragmented from a naturally occurring compound.
