There are 18 different alkane molecules that all have the molecular formula CgH18. Molecules with the same molecular formula, but different atomic connections (structural formulas) are called "constitutional isomers". See how many different alkanes, all with the same formula (CgH18) that you can draw. After you draw them, write their names. You can draw line bond, condensed, or skeletal structures (the key shows skeletal structures)

Distinguish between isomerism and resonance. Distinguish between structural and geometric isomerism. When writing the various structural isomers, the most difficult task is identifying which are different isomers and which are identical to a previously written structurethat is, which are compounds that differ only by the rotation of a carbon single bond. How do you distinguish between structural isomers and those that are identical? Alkenes and cycloalkanes are structural isomers of each other. Give an example of each using C4H8. Another common feature of alkenes and cycloalkanes is that both have restricted rotation about one or more bonds in the compound, so both can exhibit cis- trans isomerism. What is required for an alkene or cycloalkane to exhibit cis-trans isomerism? Explain the difference between cis and trans isomers. Alcohols and ethers are structural isomers of each other, as are aldehydes and ketones. Give an example of each to illustrate. Which functional group in Table 21-4 can be structural isomers of carboxylic acids? What is optical isomerism? What do you look for to determine whether an organic compound exhibits optical isomerism? 1-Bromo-1-chloroethane is optically active whereas 1-bromo-2-chloroethane is not optically active. Explain.
name and draw structural formulas for all cyclo-alkanes with the molecular formula C5H10. Be certain to include cis-trans isomers, as well as constitutional isomers
1. Considering compounds that have the same number of carbon atoms, explain why alkanes and cycloalkanes have different molecular formulas but alkenes and cycloalkanes have the same molecular formulas. 2. Draw the condensed or line-angle structure for an alkene with the formula C5H10. 3. Draw the condensed or line-angle structure for 4 more C5H10 isomers (2 additional alkenes and 2 cyclic isomers).
Give the systematic names for all alkanes with molecular formula C7H16 that do not have any secondary hydrogens.
Draw the condensed or line-angle structure for an alkene with the formula C5H10. Name 6 Structural isomers of C5H10. They should three alkene and two cycloalkane
Given the molecular formula C6H1o, draw and name: 1 alkene, 1 cyclic, and 1 alkynethat fulfill this formula (isomers). Use skeletal, line angle or expanded form in yourdrawings.
1. a. Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomers. b. Draw and name the eight cycloalkane structures of formula C6H12 that do not show geometric isomerism. c. Draw and name the four cycloalkanes of formula C6H12 that do have cis-trans isomers. 2. Each of the following descriptions applies to more than one alkane. In each case, draw and name two structures that match the description. (a) an isopropylheptane (b) a diethyldecane (c) a cis-diethylcyclohexane (d) a trans-dihalocyclopentane (e) a (2,3-dimethylpentyl)cycloalkane (f) a bicyclononane 3. 2. refer to the photo attached and answer the ff.3-33, 3-34
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?
There are 17 possible alkene isomers with the formula C6H12. Draw structures of the five isomers in which the longest chain has six carbon atoms, and give the name of each. Are any of these isomers chiral? (There are also eight isomers in which the longest chain has five carbon atoms, and four isomers in which the longest chain has four carbon atoms. How many can you find?)
Summarize the nomenclature rules for alkanes, alkenes, alkynes, and aromatic compounds. Correct the following false statements regarding nomenclature of hydrocarbons. a. The root name for a hydrocarbon is based on the shortest continuous chain of carbon atoms. b. The suffix used to name all hydrocarbons is -ane. c. Substituent groups are numbered so as to give the largest numbers possible. d. No number is required to indicate the positions of double or triple bonds in alkenes and alkynes. e. Substituent groups get the lowest number possible in alkenes and alkynes. f. The ortho- term in aromatic hydrocarbons indicates the presence of two substituent groups bonded to carbon- 1 and carbon-3 in benzene.
