Textbook Question

Using IUPAC rules, name the following molecules.
(d)

Verified step by step guidance

Identify the longest continuous carbon chain in the molecule. This chain will serve as the parent chain, and its length determines the base name (e.g., methane, ethane, propane, etc.).

Number the carbon atoms in the parent chain, starting from the end closest to the first substituent (branch or functional group) to ensure the substituents receive the lowest possible numbers.

Identify and name all substituents (e.g., alkyl groups like methyl, ethyl, etc., or functional groups like hydroxyl, halogens, etc.) attached to the parent chain.

Assign a number to each substituent based on its position on the parent chain. If there are multiple identical substituents, use prefixes such as di-, tri-, tetra-, etc., and list their positions.

Combine the names of the substituents and the parent chain into a single name. List substituents in alphabetical order (ignoring prefixes like di-, tri-, etc., for alphabetization), and separate numbers from words with hyphens and numbers from numbers with commas.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for naming based on the structure of the molecule, including the longest carbon chain, functional groups, and substituents. Understanding these rules is essential for accurately identifying and communicating the identity of organic compounds.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. Common functional groups include alcohols, carboxylic acids, and amines. Recognizing functional groups is crucial for naming compounds and predicting their reactivity.

Carbon Chain Length and Branching

The length of the carbon chain and the presence of branching significantly influence the naming of organic compounds. The longest continuous chain of carbon atoms determines the base name, while branches are indicated by prefixes. Properly identifying the main chain and any branches is vital for applying IUPAC rules correctly.

Textbook Question

In Problem 5-3, you drew the enantiomers for a number of chiral compounds. Now go back and designate each asymmetric carbon atom as either (R) or (S).

(a)

(b)

Textbook Question

3,4-Dimethylpent-1-ene has the formula CH₂=CH—CH(CH₃)—CH(CH₃)₂. When pure (R)-3,4-dimethylpent-1-ene is treated with hydrogen over a platinum catalyst, the product is (S)-2,3-dimethylpentane.

c. The reactant is named (R), but the product is named (S). Does this name change imply a change in the spatial arrangement of the groups around the chiral center? So why does the name switch from (R) to (S)?
