Study Notes
Hydroxyl Group Overview
- Chemical formula is represented as (-OH) or (HO-), characteristic of monosaccharides.
Properties of Hydroxyl Group
- Capable of forming hydrogen bonds with water, facilitating the dissolution of polar substances like sugars.
Polarity and Acidity
- Contains a polar structure due to the electronegative oxygen atom.
- Does not exhibit acidic properties; it is neutral in that regard.
Classification of Hydroxyl Compounds
- Compounds containing hydroxyl groups are classified as alcohols, typically with names ending in -ol.
Common Examples
- Ethanol is a prominent example, widely recognized as the type of alcohol found in beverages.
Role in Polymers
- Hydroxyl groups are fundamental in the structure of carbohydrates, which are essential biomolecules.
Behavior in Solution
- Hydroxyl groups can undergo ionization, losing a proton when the pH of the environment increases, affecting their reactivity.
