Chapter E, Problem E.33P

Interpretation Introduction

(a)

Interpretation:

The structure for the molecule that resembles to the given IUPAC name is to be drawn.

Concept introduction:

In the given IUPAC name, the root name indicates the longest continuous carbon chain at the end of the compound’s name. The suffix ‘amine’ refers to the amine (${\text{-NH}}_{\text{2}}$) functional group. Other, lower priority, functional groups are listed as prefixes, along with numbers indicating their positions on the longest carbon chain. Prefixes, di, tri, etc., are used to denote the number of identical substituents. The substituents are written in alphabetical order when writing the IUPAC name.

The stereochemical designation and the locators are enclosed in parenthesis at the very beginning of the name. The stereochemistry at the chiral centre is determined by assigning the priorities to the groups attached to the chiral centre on the basis of the atomic number of directly bonded atom. If the sequence of priority order $\text{1}\to \text{2}\to \text{3}$ is clockwise, the absolute configuration is R, and if it is counterclockwise, the absolute configuration is S.

Interpretation Introduction

(b)

Interpretation:

The structure for the molecule that resembles to the given IUPAC name is to be drawn.

Concept introduction:

In the given IUPAC name, the root name indicates the longest continuous carbon chain at the end of the compound’s name. The suffix ‘ol’ refers to an alcohol ($\text{-OH}$) functional group. The prefix ‘amino’ refers to the amine (${\text{-NH}}_2$) functional group. Other, lower priority, functional groups are listed as prefixes, along with numbers indicating their positions on the longest carbon chain. Prefixes, di, tri, etc., are used to denote the number of identical substituents. The substituents are written in alphabetical order when writing the IUPAC name.

In the given IUPAC name, the root name indicates the longest continuous carbon chain at the end of the compound’s name. The suffix ‘amine’ refers to the amine (${\text{-NH}}_{\text{2}}$) functional group. The prefix ‘di’ refers to the two functional groups attached to the carbon chainOther, lower priority, functional groups are listed as prefixes, along with numbers indicating their positions on the longest carbon chain. Prefixes, di, tri, etc., are used to denote the number of identical substituents. The substituents are written in alphabetical order when writing the IUPAC name.
