Chapter F, Problem F.32P

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 the highest priority functional groups are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing a 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 no need to remove ‘e’ from‘ane’, ‘ene’, or ‘yne’ ending and prefixes are used to denote the number of identical functional groups. Number the carbon chain in such a way that the functional group and the substituents attached gets 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.

(b)

Interpretation:

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

Concept introduction:

In naming organic compounds, the functional groups other than the highest priority functional groups are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing a 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 ‘carboxylic acid’ is present as the highest priority group attached directly to the ring, both the ring and the functional group established the root name. The ring is named first followed by ‘carboxylic acid’.

Number the carbon chain in a way that the functional group and the substituents attached gets 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.

(c)

Interpretation:

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

Concept introduction:

In naming organic compounds, the functional groups other than the highest priority functional groups are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing a 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 ‘amide’ is present as the highest priority group, suffix amide replaces ‘e’ from the parent chain name. The group attached to the N atom is written as a prefix to the root name with the letter ‘N’.

Number the carbon chain in a way that the functional group and the substituents attached gets 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.
