Model 5: Structural formula of butane and 2-butene HHHH H-C-C-C-C-H HHHH Butane H H-C-C-C-C-H HHHH 2-Butene Key Questions: 28.) Note 2 differences between the structural diagrams for butane and 2-butene. 29.) What does the ending -ene tell you about the hydrocarbon on the right? 30.) In the diagram on the right, number the carbons starting from the left with number 1. What does the 2 in 2-butene tell you about location of the double bond in the hydrocarbon? 31.) Draw 2-pentyne below. Draw all of the carbons first, connecting them with the appropriate type of bond. Be sure that when you add the hydrogens that there are only 4 bonds on each carbon. 32.) Draw 3-heptene below. 5
