Chapter E, Problem E.44P

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 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. 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 parent chain or ring is indicated by the respective locant number just before the suffix. Prefixes are used to denote number of identical substituents. The substituents are written in an alphabetical order when writing the IUPAC name.

(c)

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. If the highest priority group is present twice, then there is no need to remove ‘e’ from ‘ane’, ‘ene’, or ‘yne’ ending and prefixes are used to denote the number of identical functional groups. Prefixes are used to denote the number of identical substituents. 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 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.
