QUÉ SIGNIFICA HYDROXYL EN INGLÉS
Hidroxilo
Un hidroxilo es un grupo funcional químico que contiene un átomo de oxígeno conectado por un enlace covalente a un átomo de hidrógeno, un emparejamiento que puede ser simplemente entendido como una subestructura de la molécula de agua. Cuando aparece, imparte a las estructuras químicas algunas de sus propiedades reactivas e interactivas. Tenga en cuenta que -OH no debe confundirse con el ion hidróxido de agua. La forma neutra del grupo hidroxilo es un radical hidroxilo. La forma aniónica, se llama anión hidróxido; Lleva una sola carga negativa residiendo en gran parte en el oxígeno más electronegativo.
