CH 105 Lecture Notes - Lecture 3: Antioxidant, Hydrohalogenation, Halogenation
Document Summary
Alkenes and alkynes are two families of organic molecules that have multiple bonds. Unsaturated hydrocarbons are compounds that have fewer than the maximum bumber of. Alkenes are compounds that have carbon- carbon double bonds. Alkynes are compounds that have carbon carbon triple bonds. Alkenes and alkynes have low melting points and low boiling points. Trans isomers: have groups on the same side of the bond have groups on opposite sides of the bond. Constitutional isomers differ in the way the atoms are bonded to eachother. Stereoisomers differ only in the 3d arrangement of the atoms. Saturated fatty acids have no double bonds in their long hydrocarbon chains. Unsaturated fatty acids have one or more double bonds in their long hydrocarbon chains. Generally, double bonds in naturally occurring fatty acids are cis. Fats are solid at room temperature generally obtained from animal sources. Oils are liquids at room temperature usually obtained from vegetable sources.
