Document Summary

Can have other atoms, too (mostly n, o, s, p, and halogens) The number of bonds relies on valence electrons. Halogens (f, br, cl, i) 1 bond. 4 groups of electrons (bonds and lone pairs) = tetrahedral. 3 groups of electrons = trigonal planar = 120. 2 groups of electrons = linear = 180. Increase from left to right across periodic table. Increase from bottom to top on periodic table. Unsaturated hydrocarbons are compounds that have fewer than the maximum bumber of. Trans isomers: have groups on the same side of the bond have groups on opposite sides of the bond. Unsaturated fatty acids have one or more double bonds in their long hydrocarbon chains. Fats are solid at room temperature generally obtained from animal sources. Oils are liquids at room temperature usually obtained from vegetable sources. Antioxidant: (such as lycopene) is a compound that prevents an unwanted oxidation.
