What is a hydrocarbon? What is the difference between a saturated hydrocarbon and an unsaturated hydrocarbon? Distinguish between normal and branched hydrocarbons. What is an alkane? What is a cyclic alkane? What are the two general formulas for alkanes? What is the hybridization of carbon atoms in alkanes? What are the bond angles in alkanes? Why are cyclopropane and cyclobutane so reactive? The normal (unbranched) hydrocarbons are often referred to as straight-chain hydrocarbons. What does this name refer to? Does it mean that the carbon atoms in a straight-chain hydrocarbon really have a linear arrangement? Explain. In the shorthand notation for cyclic alkanes, the hydrogens are usually omitted. How do you determine the number of hydrogens bonded to each carbon in a ring structure?
A. Structural Isomerism of Alkanes Construct models for the five alkanes that have the molecular formula C6H14. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure.

C. Alkenes 1. Construct a model of ethene (C₂H4) by joining two carbon atoms with a double bond. Toggle between skeletal and full Lewis structures by clicking the C-H tool. Note the trigonal planar geometry of the bonds around each carbon atom, and that the carbon-carbon double bond has restricted rotation. Observe that the six atoms in ethene all lie in the same plane, and the double bond is a fixed geometry within the molecule. 2. Add a CH3- group to each of the doubly-bonded carbons to create a four-carbon alkene with the double bond between carbons 2 and 3. Note that the CH3- groups can be attached in two different ways: Both CH3- groups on the same side of the fixed geometry of the double bond. The two CH3- groups on opposite sides of the double bond. Click the broom to tidy up the structures; convert each to a ball-and-stick model clicking the 2D to 3D tool.
