Chapter 2, Problem 56P

Interpretation Introduction

Interpretation: The IUPAC names for all alkyl groups marked by dashed lines in the biologically important compounds should be written and nature of identified as primary, secondary or tertiary alkyl substituent.

  

Concept introduction: As per IUPAC recommendations longest chain found in a continuous manner in a branched molecule is chosen as parent chain.

The IUPAC name begins with prefix to designate the number of $\text{C}$ atoms in the longest chosen parent alkane followed by the suffix −ane. The positions of side chains or substituents are indicated by lowest numeral places before prefix.

Names of branches that occur commonly as side chains are listed below:
