- 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_forwardDraw the structure(s) of all of the branched alkene isomers, C6H12, that contain 2 methyl branches.arrow_forwardFor the following, you must draw an appropriate structure that has the chemical formula C5H7O2Cl with the indicated functional group(s) and/or property. In each case, identify any other functional groups in the molecule you draw, that were not indicated in the question. You may use Lewis or bond- line structures to draw your molecules. You may not use the same structure to answer more than 1 question. a) An acyclic molecule that cannot form hydrogen bonds with itself b) A tertiary chloride c) A cyclic etherarrow_forward
