Concept explainers
(a)
To determine: The number of hydrogen atoms in the hydrocarbon that has nine carbon atoms, three double bonds and one ring.
Interpretation: The number of hydrogen atoms in the hydrocarbon that has nine carbon atoms, three double bonds and one ring is to be calculated.
Concept introduction: The compounds that have double bonds or triple bonds are called unsaturated compounds.
(b)
To determine: The number of elements of unsaturation implied by the molecular formula
Interpretation: The number of elements of unsaturation implied by the molecular formula
Concept introduction: The compounds that have double bond or triple bond are called unsaturated compounds. Alkenes are the unsaturated compounds that have double number of hydrogen atoms than the number of carbon atoms.
(c)
To determine: The five structures of the compound that have the molecular formula
Interpretation: The five structures of the compound that have the molecular formula
Concept introduction: The structure of the compound is the graphic representation of the molecular formula that shows that the arrangement of the atoms in the compound.
The compounds having same molecular formula and different structural arrangement of the atoms are called isomers of that compound. Isomers are of two types; structural isomers and stereoisomer. The Structural isomers can be chain isomer, position isomer and functional group isomers.

- 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.
