Chapter F, Problem F.31P

Interpretation Introduction

(a)

Interpretation:

For the given compound, the IUPAC name 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 the functional group and substituents on the parent chain or ring is indicated by the respective locant number just before the suffix. The substituents groups are written in alphabetical order when writing the IUPAC name.

(b)

Interpretation:

For the given compound, the IUPAC name 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 ‘amide’ is present as the highest priority group attached directly to the ring, both the ring and the functional group establish the root name. The ring is named first followed by ‘carboxamide’.

Number the carbon chain in a way that the functional group and the substituents attached get 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 substituent groups are written in alphabetical order when writing the IUPAC name.

(c)

Interpretation:

For the given compound, the IUPAC name 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 no need to remove ‘e’ from‘ane’, ‘ene’, or ‘yne’ ending and prefixes are used to denote number of identical functional groups. Number the carbon chain in a way that the functional group and the substituents attached gets lowest number. The position of the functional group and substituents on parent chain or ring is indicated by the respective locant number just before the suffix. The substituent groups are written in alphabetical order when writing the IUPAC name.
