Chapter 22, Problem 109RQ

Interpretation Introduction

Interpretation:

The condensed structures and IUPAC (International Union of Pure and Applied Chemistry) names for all the saturated alcohols with three or fewer carbon atoms per molecule are to be represented.

Concept Information:

Alcohol is an organic compound in which an OH group is attached to the carbon atom. The naming of the alcohol group is done by replacing –e with an –ol.

The IUPAC names are developed for each compound for their systematic categorization.

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-.

Saturated alcohols are defined as the alcohol groups in which the carbon atoms have single bonds between them. They are polar in nature and are more water soluble than any other hydrocarbon.
