Chapter 9, Problem 29P

(a)

Interpretation Introduction

Interpretation:

The name of the given ether has to be given.

Concept introduction:

IUPAC naming of Ether compounds:

An Ether group consists of oxygen atom attached between two carbon chains. The shorter of two chains becomes the first part of the name with ‘ane’ changes to ‘oxy’ and the longer alkane becomes the suffix of the name of the ether.

When the Oxygen is not at the terminal position of main chain of alkane, then the shorter alkyl group and the ether group together are treated as a side chain and prefixed with its position of bonding on the main chain.

Interpretation Introduction

Interpretation:

The name of the given alcohol has to be given.

Concept introduction:

Nomenclature of alcohols:

• The suffix used to denote the $\text{-OH}$ group will be “ol” and this has to be replaced with “e” at the end of the name of the parent hydrocarbon.
• The longest chain containing the functional group will be the parent chain.
• While numbering the parent chain, care must be taken to number in a direction that gives the functional group suffix the lowest possible number.
• The functional group suffix has to get the lowest possible number in the presence of a functional group suffix and a substituent.
• There is no need to designate the position of a functional group suffix in a cyclic compound since it is assumed to be at the first position.
