A hydrogen bond donor is a type of chemical compound that is characterized by its ability to donate protons, which are essentially hydrogen atoms. In this context, it should be noted that the protons in question are those that are covalently bound to the compound. As an illustration, let's consider water, which has two hydrogen atoms that are covalently attached to its oxygen atom. This unique arrangement allows water to form hydrogen bonds with other molecules, demonstrating the importance of hydrogen bond donors in various chemical processes.Could you please specify the number of hydrogen bond donors present in the molecule?
