The two
Introduction:
Structural isomers are also known as constitutional isomers having same chemical formula but they have different patterns of bonding because they are connected in a different order.

- Write the molecular formula of each alkane.arrow_forwardWhat 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_forwardHow does the structure of a cycloalkane differ from that of a straight-chain or branched-chain alkane?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_forwardGive the structures and IUPAC names of all constitutional isomers of C6H14. What is the structure of 3-ethyl-2,4,6-trimethyloctane? What is the structure of 3-ethyl-3-methylpentane?arrow_forwardName and draw structural formulas for all alkenes with the molecular formula C5H10. As you draw these alkenes, remember that cis and trans isomers are different compounds and must be counted separatelyarrow_forward
- explain structural isomerism in aliphatic alkanes and geometric isomerism in alkenes. Describe structural isomerism and the different types that exist. With the aid of diagrams use the molecular formulae C5H12 and C5H10 to explain structural isomerism in aliphatic alkanes and alkenes. Describe geometric isomerism. With the aid of diagrams use the molecular formula C5H10 to explain geometric isomerism in alkenes.arrow_forwardWrite the condensed structural formulas for two alkenes and one alkyne that all have the molecular formula C6H10.arrow_forwardGive the different isomers formed by C5H8 along with their IUPAC name.arrow_forward
- (5c-201-5) Draw a skeleton structure and give the IUPAC name of a molecule with one alcohol group, 5 total carbons, and one methyl substituent group.arrow_forwardIn organic chemistry, is it only when naming cycloalkanes that you do not put a hyphen between the substituent and the parent ring?arrow_forwardGasohol is a mixture of 90% gasoline and 10% ethanol, CH 3CH 2OH. Ethanol is considered an environmentally friendly fuel additive because it can be made from a renewable source—sugarcane. Ethanol burns in air to form CO 2 and H 2O, and, like the combustion of alkanes, this reaction also releases a great deal of energy. Write a balanced equation for the combustion of ethanol.arrow_forward
