Chapter E, Problem E.45P

Interpretation Introduction

(a)

Interpretation:

The IUPAC name for the given compound is to be assigned.

Concept introduction:

In naming organic compounds, the functional groups, other than highest priority functional groups, are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing functional group. Remove the “e” from the normal ‘ane’, ‘ene’, or ‘yne’ ending and add the suffix that corresponds to the highest-priority functional group. Number the carbon chain in a way the functional group and the substituents attached to it gets the lowest number. The position of the functional group and substituents on the parent chain or ring is indicated by the respective locant number just before the suffix. The substituents are written in alphabetical order when writing the IUPAC name.

(b)

Interpretation:

The IUPAC name for the given compound is to be assigned.

Concept introduction:

In naming organic compounds, the functional groups other than highest priority functional groups are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing the functional group. Remove the “e” from the normal ‘ane’, ‘ene’, or ‘yne’ ending and add the suffix that corresponds to the highest-priority functional group. If the highest priority group is present twice, there is no need to remove ‘e’ from‘ane’, ‘ene’, or ‘yne’ from the ending, and prefixes are used to denote the number of identical functional groups. Number the carbon chain in a way that the functional group and the substituents attached get the lowest number. The position of functional group and substituents on the parent chain or ring is indicated by the respective locant number just before the suffix. The substituents are written in an alphabetical order when writing the IUPAC name.

The substituents are written in alphabetical order when writing the IUPAC name. The stereochemistry of bond is indicated by $\text{E/Z}$ notation. $\text{E}$ represents the trans double bond where the same priority groups are on opposite side of double bond. $\text{Z}$ represents the cis double bond where the same priority groups are on same side of the double bond.
