Chapter E, Problem E.39P

Interpretation Introduction

(a)

Interpretation:

For the given corresponding molecule, the IUPAC name is to be written.

Concept introduction:

The name of a compound, other than those containing only a double or a triple bond, halogen, nitro group, and ether, is made up of three parts. A prefix shows the presence of additional functional groups like halo, nitro, etc. The root name indicates the number of carbon atoms in the longest chain, along with the presence and position of $\text{C}=\text{C and C}\equiv \text{C}$ if present. Finally, a suffix corresponding to the highest priority group replaces the ‘e’ in the alkane/alkene/alkyne root name along with its position indicator. The position indicator (locant) may be dropped if redundant. An exception to replacing the ‘e’ is nitriles. All other groups, of lower priority, are treated as substituents and appear in the prefix. In case of aldehydes and ketone, if the carbonyl carbon is in the longest chain of carbon atoms, it is also counted toward its length.
