Explanation:
Detailed explanation-1: -In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry, alcohols and carboxylic acids contain one or more hydroxy groups.
Detailed explanation-2: -The hydroxyl group has hydrophilic properties. As the oxygen atom has higher electronegativity, the electron pair from the water hydrogen atom is attracted to it, creating a negative charge. This is also a polar group and enhances hydrogen bonding in organic compounds.
