1.1AlkanesTextbook pp. 8–17Vocabularyorganic compoundhydrocarbonsaturated hydrocarbonalkanecyclic alkanealkyl groupsubstituent groupstructural isomercomplete combustionalkyl halideMAIN IDEA: Hydrocarbons contain hydrogen and carbon. In a saturated hydrocarbon,the atoms of carbon are bonded to each other by single bonds. Structural isomers are compoundsthat have the same molecular formula but different molecular geometry. Alkanesmay have a straight-chain structure or a ring structure. Substituent groups may be attachedto the parent structure. Alkyl halides are alkanes in which halogen atoms have substitutedfor one or more hydrogen atoms.1. Name two alkanes that are used as fuels to heat homes and solder torches. K/ULearning TipLine DiagramsIn a line diagram, imagine that thereis a carbon atom at the end of everyline and at the intersection of everyline. Each one is surrounded by themaximum number of hydrogen atoms.2. Name and describe three common ways of depicting the structures of organiccompounds. K/U3. Indicate whether each of the following statements is true or false. If you thinka statement is false, rewrite it to make it true. K/U(a) A substituent group is any atom or group that replaces carbon in anorganic molecule.(b) A structural isomer is a compound that has the same molecular formula asanother compound, but a different structure.Learning TipMemory Aid: Table of TermsYou might find it helpful to createa 3-column table summarizing thenaming of alkanes with 1 to 10carbon atoms. List the unbranchedstraight-chain alkanes, theunbranched cycloalkanes, and thealkyl groups.4. An alkyl group consisting of a 3-carbon chain and 7 hydrogen atoms is calleda(n) _________ group. K/U5. Which of the following is not a saturated hydrocarbon? K/U(a) 1,3-dichlorobutane(b) 2,4-dimethylpentane(c) 2,3,4-trimethyloctane(d) 1,4-diethylcyclohexane2 Unit 1 • Organic Chemistry NEL

Is the following statement true or false? If you think the statement is false,rewrite it to make it true: Cyclohexane contains 6 carbon atoms with eachcarbon atom bonded to 4 atoms, so one molecule of cyclohexane contains aBiology total of 1224 Study atoms.
