(a)
Interpretation:
Two structures of the given compound are to be drawn using the abbreviations for substituent groups abbreviated as methyl groups for one structure and a five-carbon skeleton, two methyl groups, and a tert-butyl group for other structure is to be shown.
Concept introduction:
The skeletal structure of a compound is represented by the line having several vertices. These vertices in the skeletal structure represent the carbon atoms presents in the structure. In the skeletal structure, the valence of the carbon is satisfied by the hydrogen atoms which are not shown. If any atom other than carbon and hydrogen is present in the molecule then it is denoted by its symbol in the skeletal structure.

- 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_forward2. a) Explain what structural feature of the double bond is required for an alkene to exhibit cis-trans (geometric) isomerism? b) Which of the following alkenes can exhibit cis-trans isomerism?

Complete the table by stating the systematic names and drawing the structural formulae of THREE structural isomers of C3H$Cl. Systematic Name Structural Formula b) A chemical test can be performed quickly in a school laboratory to distinguish between cyclohexanol and 1-methylcyclohexanol. Identify the reagent used in this test and describe the expected observations.arrow_forward14. One way of naming ethers is to name the two alkyl groups attached to the oxygen atom in alphabetical order and add the word ether. If the two alkyl groups are the same, we use the prefix di-, for example, as in dimethyl ether.
