Chapter A, Problem A.42P

Interpretation Introduction

(a)

Interpretation:

The structure for the given compound is to be drawn and its IUPAC name is to be written.

Concept introduction:

An alkane is said to be substituted if a hydrogen atom of the alkane is replaced by another atom or group of atoms. In the name of a molecule, the root name defines the number of carbon atoms in the longest chain. The names of the substituents and their respective locant numbers show the carbon atoms of the root to which the substituents are attached.

When writing the IPUAC name, if there are two possible roots, the root is chosen such that it has maximum number of substituents attached. The root is numbered such that the substituents attached get the lowest locant numbers. First, the substituents are written alphabetically with their respective locant numbers. The root name is written at the end. Two numbers are separated by a comma while a number and a word is separated by a hyphen.

(b)

Interpretation:

The structure for the given compound is to be drawn and its IUPAC name is to be written.

Concept introduction:

An alkane is said to be substituted if a hydrogen atom of the alkane is replaced by another atom or group of atoms. From the number of carbon atoms in the longest carbon chain the root name is identified. The names of the substituents and their respective locant numbers show the carbon atoms of the root to which the substituents are attached.
