What is an example of classifying in chemistry

Explanation: For example, the 108.9° bond angle in methanol shows the effect of the methyl group, which is larger than the hydrogen atom of water. One way of classifying alcohols is based on which carbon atom is bonded to the hydroxyl group. If this carbon is primary (1°, bonded to only one other carbon atom), the compound is a primary alcohol.

Most chemical reactions can be classified into one or more of five basic types: acid–base reactions, exchange reactions, condensation reactions (and the reverse, cleavage reactions), and oxidation–reduction reactions.
