Ethanol is an example of a Hydroxyl group.

This is the structural formula (though there are lines connecting the H's to the C's)

H H

Hydroxyls are the resulting molecules formed when UV-C radiation reacts with water molecules. This reaction will strip water molecules of one of their hydrogen atoms to create the hydroxide anion (OH-) and the free Hydrogen radical will also form hydrogen peroxide (H2O2) by combining with other hydrogen and oxygen atoms. Water molecules and the hydroxyl (OH-) apparently have a signature absorption of infrared energy at the 3.0 micrometer wavelength.

R-OH

It depends on where the functional group is. It almost always raises melting and boiling temperature and makes it more hydrophilic. If it's on the same carbon as a double-bonded oxygen, it decreases pKa (i.e. makes the compound more acidic)

Assuming that you meant "hydroxyl" then a hydroxyl group is functional group that is made up of an oxygen (O) covalently bonded to a hydrogen (H) where the rest of the molecule is represented by R: R-OH. Hydroxyl groups are the functional group of alcohols. Example being ethanol: C2H5OH

The hydroxyl ion is composed of one hydrogen and one oxygen atom. It is an anion with a charge of -1. Its formula is OH-.
