Root Explanation

The word 'triol' originates from the French word 'triol', which refers to a type of threefold or triple arrangement. It is derived from 'tri-' (meaning three) and the suffix '-ol', which is often used in chemistry to denote alcohols or compounds. Therefore, 'triol' refers to a compound containing three hydroxyl (-OH) groups.

Memory Tip

Think of 'tri-' meaning three, and picture a compound that has three parts or groups. This helps you remember that 'triol' refers to a substance with three hydroxyl groups.
