Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Explanation of Solution

The IUPAC name of the given compound is 2-isobutyl-3-isopropylhexanal.

One should follow the given steps to derive the structure of an aldehyde from its IUPAC name. The first step is finding of longest parent chain that contains an aldehyde group. The second step is changing of -e ending of the parent alkane to the suffix -al. However, when an aldehyde (CHO) group is bonded to a ring then after naming of ring, the suffix -carbaldehyde is used. The third step is numbering of chain or ring by putting the CHO group at C1, and using the general rules of nomenclature.

The given IUPAC name suggests the presence of 6 C's in the longest chain containing CHO group. On this chain, the isobutyl group is substituted at C2, and the isopropyl group is substituted at C3.

Thus, the structure corresponding to the given IUPAC name is,
