Here's why:
* Hydroxyl group is a functional group, not a molecule. It's a specific arrangement of atoms (one oxygen and one hydrogen) that's attached to a larger molecule, giving that molecule specific chemical properties.
* Inorganic molecules lack carbon-hydrogen bonds. Hydroxyl groups are typically found in organic molecules (those containing carbon and hydrogen), not inorganic ones.
Think of it this way:
* The hydroxyl group (-OH) is like a building block. It's not a complete house by itself. It's used to create various types of organic "houses" (alcohols) with different structures and properties.
* Inorganic molecules are like other types of structures. They might be made of bricks, stones, or metal, but they don't use the same building blocks as organic molecules.
