Question

Select the complete IUPAC name for the compound, including the correct (R) or (S) designation.

Answer 1

The compound can be named as pentanal.

Step-by-step explanation:

The compound given can be named as follows:

1. Determine the longest continuous carbon chain, which is 5 carbons in this case and is referred to as pentane. Give the substituents a locant number, which is 3 for the aldehyde group.
2. Since there is an aldehyde group, the compound is named as pentanal.
3. The (R) or (S) designation for the compound would be determined based on the stereochemistry at the chiral center, if present. However, the stereochemistry is not mentioned in this question, so the (R) or (S) designation cannot be determined.
