Chapter 11 Introduction to Organic Chemistry: Alkanes 11.2 Alkanes General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 1 Names of Alkanes The names of alkanes are determined by the IUPAC (International Union of

Pure and Applied Chemistry) system use a prefix to indicate the number of carbons in a chain end in -ane General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 2 IUPAC Names for Alkanes

General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 3 Learning Check A. Give the name of each compound: 1) CH3CH3 2) CH3CH2CH3 3) CH3CH2CH2CH2CH2CH3 B. Write the condensed structural formula of pentane.

General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 4 Solution A. Give the name of each compound: 1) CH3CH3 ethane 2) CH3CH2CH3

propane 3) CH3CH2CH2CH2CH2CH3 hexane B. Write the condensed structural formula of pentane. CH3CH2CH2CH2CH3 General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc.

5 Structural Formulas Alkanes are written with structural formulas that are expanded to show each bond condensed to show each carbon atom and the attached hydrogen atoms General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc.

6 Line-Bond Formulas Because each C atom has a tetrahedral arrangement, the order of atoms is not a straight line, but a zigzag pattern. A line-bond formula abbreviates the carbon atoms and shows only the zigzag pattern of bonds from carbon atom to carbon atom.

7 Types of Structural Formulas General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 8 Rotation Around a CC Single Bond

The groups attached to a CC single bond rotate around the bond give different relative structural arrangements called conformations General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 9 Writing Structural Formulas Carbon atoms in a chain

maintain their tetrahedral shape are connected in a zigzag pattern are drawn as two-dimensional can be written in several conformations General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 10 Structural Arrangements of Butane

Rotation of the end CH3-groups provides different structural arrangements for butane. General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 11 Hexane has Six Carbon Atoms Hexane is an alkane with 6 carbon atoms in a continuous chain

has a zigzag look because each carbon atom is at the center of a tetrahedron is represented by a ball-and-stick model as General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 12 Learning Check A. Draw the condensed structural formula of

B. What is its molecular formula? C. What is its name? General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 13 Solution A. Draw the condensed structural formula: CH3CH2CH2CH2CH3 B. What is its molecular formula? C. What is its name?

General, Organic, and Biological Chemistry C5H12 pentane Copyright 2010 Pearson Education, Inc. 14 Learning Check Draw the condensed structural formula for:

A. Ethane B. Heptane General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 15 Solution Draw the condensed structural formula for: A. Ethane

CH3CH3 B. Heptane CH3CH2CH2CH2CH2CH2CH3 General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 16 Cycloalkanes Cycloalkanes are cyclic alkanes

have 2H fewer than the alkane are named by using the prefix cyclo- before the name of the alkane chain with the same number of carbon atoms General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 17 Cycloalkanes (continued) The structural formulas

of cycloalkanes are often shown as geometric figures General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 18 Cycloalkanes (continued) General, Organic, and Biological Chemistry

Copyright 2010 Pearson Education, Inc. 19 Learning Check Name the following: A. CH3CH2CH2CH3 B. C. CH3CH2CH2CH2CH2CH2CH2CH3 D. General, Organic, and Biological Chemistry

Copyright 2010 Pearson Education, Inc. 20 Solution Name the following: A. CH3CH2CH2CH3 butane B.

cyclopropane C. CH3CH2CH2CH2CH2CH2CH2CH3 octane D. cyclohexane General, Organic, and Biological Chemistry Copyright 2010 Pearson Education, Inc. 21
