- Summarize the nomenclature rules for alkanes, alkenes, alkynes, and aromatic compounds. Correct the following false statements regarding nomenclature of hydrocarbons. a. The root name for a hydrocarbon is based on the shortest continuous chain of carbon atoms. b. The suffix used to name all hydrocarbons is -ane. c. Substituent groups are numbered so as to give the largest numbers possible. d. No number is required to indicate the positions of double or triple bonds in alkenes and alkynes. e. Substituent groups get the lowest number possible in alkenes and alkynes. f.

- Constitutional isomers are compounds which have the same molecular formula but different structural formulae. They are different compounds with different physical and chemical properties.a. Rearrange your model of n-hexane to make as many possible isomers of C6H14 as you can. Draw the structural formula and write down the IUPAC name for each isomer that you make.b. Constitutional isomers can also have different functional groups. Make all possible isomers of C3H8O. Write down the structural formulae and IUPAC names for all the compounds you make. Hint: Consider alcohol and ether functional groups.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.
