Concept explainers
(a)
Interpretation:
The number of hydrogen atoms present in the straight-chain alkane having 4 carbon atoms should be determined.
Concept Introduction:
(b)
Interpretation:
The number of hydrogen atoms present in the straight-chain alkane having 6 carbon atoms should be determined.
Concept Introduction:
Alkanes are hydrocarbons that is they contain only carbon and hydrogens attached by single bonds only. The general formula for alkane is Cn H2 n + 2, where n is number of carbon atoms.
(c)
Interpretation:
The number of hydrogen atoms present in the straight-chain alkane having 17 carbon atoms should be determined.
Concept Introduction:
Alkanes are hydrocarbons that is they contain only carbon and hydrogens attached by single bonds only. The general formula for alkane is Cn H2 n + 2, where n is number of carbon atoms.
(d)
Interpretation:
The number of hydrogen atoms present in the straight-chain alkane having 20 carbon atoms should be determined.

- What is the difference in bonding and in the general molecular formula between an alkene and an alkane with the same number of carbon atoms?arrow_forwardExplain why two different straight-chain alkanes could not be constitutional isomers.arrow_forwardWrite the molecular formula of each alkane.arrow_forward
- Use the generic formula for alkanes (CnH2n+2) to derive molecular and condensed structural formulas for: a. Propane, 3 carbon atoms b. Octane, 8 carbon atoms c. Butane, 4 carbon atomsarrow_forwardHow does the structure of a cycloalkane differ from that of a straight-chain or branched-chain alkane?arrow_forwardDistinguish 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.
