Chapter 22, Problem 100RQ

Interpretation Introduction

Interpretation:

The IUPAC (International Union of Pure and Applied Chemistry) names of the given compounds are to be written.

Concept Information:

International Union of Pure and Applied Chemistry is abbreviated as IUPAC.

It is a standard naming system for all organic and inorganic compounds.

Hydrocarbons are compounds containing carbon $\left(\text{C}\right)$ and hydrogen $\left(\text{H}\right)$ atoms. They are alkanes, alkenes, alkynes, and aromatic hydrocarbon.

An organic compound has three basic parts while inorganic compounds have two basic parts for naming of compounds.

General rules for IUPAC nomenclature of organic compounds

•Recognize the functional group in the compound to determine the suffix of the name like, -ane for alkan, -ene for alken, -yne for alkyne, -ol for alcohol etc.

•Find the longest continuous carbon chain that contains the functional group and count the number of carbon atoms in this chain to determine the prefix of the compound name like, Meth- for single carbon, eth- for 2 carbon chain, prop- for 3 carbon chain, etc.

•Number the carbons in the longest carbon chain by stating with the carbon at the end closest to the functional group.

•Look for any branched groups, name them and assign the number of the carbon atom to which the group is attached like 2,4-.
