Chapter A, Problem A.10P

Interpretation Introduction

Interpretation:

The IUPAC name of the given compound is to be written.

Concept introduction:

The root name is determined by the number of carbon atoms in the longest straight chain as an alkane. In the case of a ring compound, the root name is cycloalkane. When the compound contains both a ring and a straight chain, the root depends on which of the two contains more carbon atoms. If the ring is smaller, then it is treated as a substituent and named cycloalkyl. Any substituents are then numbered and named at the start of the complete name. The numbering of the substituents is done so as to get the smallest possible numbers. If more than one type of substituents is present, then they are listed alphabetically.

When an alkyl chain is attached to the root at a carbon other than the end carbon (#1), the longest chain of the substituent is determined from the point of attachment. The remaining part of the chain is treated as a substituent on this chain.
