Here's a breakdown:
* Glyc-: This part comes from the Greek word "glukos," meaning "sweet." This is because many glycols have a sweet taste.
* -ol: This suffix indicates that the molecule is an alcohol, meaning it has at least one hydroxyl group (-OH) attached to a carbon atom.
Therefore, "glycol" indicates a molecule with two hydroxyl groups, which gives it unique chemical properties and makes it useful in various applications, like antifreeze and polyester production.
