(a)
Interpretation:
The number of carbon atoms present in the given straight-chain alkane compound having twenty hydrogen atoms have to be determined.
Concept Introduction:
The alkanes are simple organic compounds. These alkane compounds have carbon- carbon single bond. The molecular formula of alkane compounds can be given as
The three types of alkane compounds are classified as linear chain alkane, branched alkane and cycloalkane. Straight-chain alkane: The carbon and hydrogen atoms are present in straight chain is known as straight-chain alkane. It also resembles snake-like structure. Branched-chain alkane: The carbon and hydrogen atoms are arranged in branched structure. Both the chain compounds have same molecular formula. The general formula of a straight-chain alkane and a branched-chain alkane compounds are given as

- How does the structure of a cycloalkane differ from that of a straight-chain or branched-chain alkane?arrow_forwardWhat is meant by the term “unsaturated hydrocarbon”? What structural feature characterizes unsaturated hydrocarbons?arrow_forwardWhat is the difference in bonding and in general molecular formula between an alkene and a cycloalkane with the same number of carbon atoms?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_forward4.2 What is an alkane?arrow_forward. With very reactive agents, such as the halogen elements, alkanes undergo reactions, whereby a new atom rep laces one or more hydrogen atoms of the alkane.arrow_forward
