- 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?arrow_forwardSummarize 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.arrow_forwardAlcohols A, B and C all have the composition C4H 100. Molecules of alcohol A contain a branched carbon chain and can be oxidized to an aldehyde; molecules of alcohol B contain a linear carbon chain and can be oxidized to a ketone; and molecules of alcohol C can be oxidized to neither an aldehyde nor a ketone. Write the Lewis structures of these molecules.arrow_forward
- 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.arrow_forwardAlkanes are hydrocarbons containing only single bonds. Acyclic alkanes have carbon atoms arranged in chains, whereas cycloalkanes have carbon atoms arranged in one or more rings. How many hydrogen atoms are in an acyclic alkane with 6 carbon atoms?arrow_forwardAlkenes and alkynes react similarly to each other. Hydrogenation, halogenation, and hydration reactions are all types of addition reactions in which the reagent adds across the multiple bond of the reactant • Hydrogenation is the addition of hydrogen gas in the presence of a catalyst such as platinum, palladium, or nickel. • Halogenation involves a reaction with a halogen such as Cl₂ or Br₂ to produce a dihaloalkane or dihaloalkene product. Hydration reactions take place when alkenes or alkynes react with water in the presence of a strong acid catalyst to yield an alcohol. ▼ Part A Predict the product of the reaction of 1-butene with bromine. Enter the IUPAC name. ▸ View Available Hint(s) Submit ▾ Part B An alkyne undergoes hydrogenation to produce an alkane as follows: 04 RC=CR + 2H₂ Q Pd catalyst alkane Predict the product and draw it.

Describe geometric isomerism. With the aid of diagrams use the molecular formula C5H10 to explain geometric isomerism in alkenes.arrow_forwardWrite the structural formula for propylene glycol, 1,2-propanediol. Why is it classified as an alcohol? Is it a polar molecule? Should it be miscible with water?arrow_forward
