Answer to Problem 21.43P

The IUPAC name for the given compound is 3, 4-diethyl-2-methylhex-3-enal.

Explanation of Solution

The given compound is an aldehyde.

One should follow the given steps to give the IUPAC name of an aldehyde. 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 structure shows the presence of six C's in the longest chain. On this chain, an aldehyde group is substituted at C1, the one methyl group is substituted at C2, the C=C bond is present between C3 and C4, and both atoms are substituted with one ethyl group.

Interpretation: The IUPAC name for the given compound is to be stated.

Concept introduction: One should follow the given steps to give the IUPAC name of an aldehyde. 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.

Answer to Problem 21.43P

The IUPAC name for the given compound is 3, 4-diethylhexanal.

Explanation of Solution

The given compound is an aldehyde.

One should follow the given steps to give the IUPAC name of an aldehyde. 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 structure shows the presence of six C's in the longest chain. On this chain, an aldehyde group is substituted at C1, and both C3, and C4 atoms are substituted with one ethyl group.

Interpretation: The IUPAC name for the given compound is to be stated.

Concept introduction: One should follow the given steps to give the IUPAC name of a ketone. The first step is finding of longest parent chain that contains a carbonyl carbon. The second step is changing of -e ending of the parent alkane to the suffix -one. The third step is numbering of chain to give the least number to carbonyl carbon, and using the general rules of nomenclature.

Answer to Problem 21.43P

The IUPAC name for the given compound is (E)-2, 5-dimethyloct-5-en-4-one.

Explanation of Solution

The given compound is a ketone.

One should follow the given steps to give the IUPAC name of a ketone. The first step is finding of longest parent chain that contains a carbonyl group. The second step is changing of -e ending of the parent alkane to the suffix -one. The third step is numbering of chain to give the least number to carbonyl carbon, and using the general rules of nomenclature.

The given structure shows the presence of eight C's in the longest chain. On this chain, the C=O group is substituted at C4, the one methyl group is substituted, both at C2 and C5, and the C=C bond is present between C5 and C6. Since the high priority groups are present opposite to each around the C=C bond, the prefix used for the nomenclature is E.
