Have a corbonyl group on the end of the carbon chain. 12 of 20 what is a carboxylic acid? contain a carbonyl group and hydroxyl group on the same carbon 13 of 20 what is an amine? have a NH2 group as a alkyl branch 14 of 20 what is a nitrile? have a C(triple bond)N named as an alkane. 15 of 20 what is the definition of structural isomers? compounds with the same molecular formula but different structure/structural formula. 16 of 20 what is the definition of chain isomerism? compounds with the same molecular formula but with a different arrangement of the carbon skeleton. 17 of 20 what is the definition of position isomerism? a compound that have the same molecule formula but with different functional group in a different postion. 18 of 20 what is functional group isomerism? Compound with the same molecular formula but with the atoms arranged into functional groups. 19 of 20 What is stereoisomerism? two molecules with the same structural formula but the atoms/bonds are arranged differently in space. 20 of 20
