Introduction to Organic Chemistry: Alkanes Because there are so many different organic compounds, we must group them into classes based on their structure. The simplest class of organic compounds is the alkanes : An alkane is a compound that contains only C and H atoms, and contains only single bonds. What are some examples of alkanes? Where do alkanes come from? What are the uses of alkanes? What is the general molecular formula of an alkane? How many constitutional isomers have the molecular formula C 5 H 12 ?

Conformations of Butane Consider rotations around the central C—C bond the molecule n -butane (the straight- chain C 4 H 10 alkane). What are the conformations that result from rotations around this central bond? What are the relative energies of these conformations? Reading : Section 2.3 Chemistry S-20ab Week 1 18
