Interpretation Introduction

Interpretation:

The structure of 1, 2-butanediol needs to be drawn.

Concept introduction:

The organic compounds generally contain carbon atoms. The naming of organic compounds is done by considering three main terms which are prefix, suffix and the root name. The longest chain in the compound is first identified and named that will be the root name for the compound. For example, if there are 3 carbon atoms in the longest chain, the root name will be “prop”. To determine the suffix, functional group should be identified. In the last step, side groups are identified and named. Prefix is used to give number of side groups and substituent’s present on the main carbon chain.

Explanation of Solution

The given compound is 1, 2-butanediol. As the name suggests, there are 2 −OH groups at 1^st and 2^nd position in the main carbon chain containing 4 carbon atoms.
