Chapter 20, Problem 52QAP

Interpretation Introduction

Interpretation:

The naming of benzene when it is as a substituent in another molecule should be explained with the help pf two examples.

Concept Introduction:

• The International Union of Pure and Applied Chemistry-IUPAC has developed a method for systematically naming organic compounds.
• The name given to a compound according to the IUPAC nomenclature consists of several parts.
1. The suffix that is used to indicate the main functional group of the structure.
2. Name of the chain that is used to identify the main carbon chain of the compound.
3. The prefixes that are used to indicate the substituent groups.
4. The numbers that are used to indicate the places at which the substituent groups, additional groups and the main functional groups are attached to the chain.

Number of carbon atoms	Root name	Name of the correspondingHydrocarbon
1	meth	Methane
2	eth	Ethane
3	prop	Propane
4	but	Butane
5	pent	Pentane
6	hex	Hexane
