Chapter 12.8, Problem 1QQ

Interpretation Introduction

Interpretation:

The correct option among the given options for the relationship between an alkyl group and its parent alkane has to be chosen.

Concept Introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry).  IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix represents the substituent present in the molecule and its position in the root name.

Suffix denotes the presence of functional group if any in the molecule.  It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.

Root word represents the longest continuous carbon skeleton of the organic molecule.

For naming the alkyl groups, the parent alkane is found out by counting the number of carbon atoms and then replacing “-ane” with “-yl” in the name.  The alkyl group is obtained by removing a hydrogen atom from the parent alkane.
