Final-Answer:
Here are the functional group isomers of pente-2-ene and butanoic acid:
* Pente-2-ene
* 2-Methylbut-1-ene
* 3-Methylbut-1-ene
* 2-Methylbut-2-ene
* 3-Methylbut-2-ene
* Butanoic acid
* Ethyl acetate
* Methyl propionate
* Ethyl propionate
* Propyl acetate
Functional group isomers are molecules that have the same molecular formula but different functional groups. In the case of pente-2-ene, the functional groups are the alkene group and the methyl group. The alkene group is a double bond between two carbon atoms, and the methyl group is a carbon atom bonded to three hydrogen atoms. The functional groups of butanoic acid are the carboxylic acid group and the methyl group. The carboxylic acid group is a carbon atom bonded to a hydroxyl group and a carboxyl group, and the methyl group is a carbon atom bonded to three hydrogen atoms.
