Chapter 14, Problem 14.99EP

(a)

Interpretation Introduction

Interpretation:

The IUPAC name of given ether has to be assigned.

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.

IUPAC rules for naming ether:

• ✓ The base name is found from the longest carbon chain present in ether.
• ✓ The suffix –yl has to be changed to –oxy in order to obtain the alkoxy group name.  For example, ethyl becomes as ethoxy, methyl becomes as methoxy etc.
• ✓ Alkoxy name has to be placed first with the number (carbon atom to which the alkoxy group is attached) followed by the base name.
