For an aldehyde, drop the -e from the alkane name and add the ending -al. Write the names of the compounds in Question 1. Write the structures from the following names: 4-methyl cyclohexanone trans-3-methyl-2-pentenal cis-2,3-dimethylcyclohexanone 1,3-dihydroxypropanone 4-isopropyl-2-methylheptane 6-methyl-4-isopropylheptane 2,5-dimethyl-4-n-propylhexane structural isomers geometric isomers enantiomers structural isomers geometric isomers structural isomers Name the following compounds (a) (R)-3-hydroxy-2-methylpropanal (b) 2-methyl-3-pentanone (c) (2S)-2-ethyl-3-methylpentanal (d) (R)-3-methylcyclopentanone 2. So, to name a ketone, we need to choose the parent chain such that it is the longest carbon chain contains the C=O group: The locant indicating the position of the carbonyl group can be placed before the parent or before the suffix “one.”  Both names are acceptable according to the IUPAC recommendations.
