Drug-like molecules are a specific category of molecules that are usually characterized by having no more than 5 Hydrogen bond donors. A Hydrogen bond donor is a chemical group that has the ability to donate a hydrogen atom to another molecule during a chemical reaction. Molecules that have more than 5 Hydrogen bond donors are less likely to pass through cell membranes, which will make it difficult for them to reach their intended target in the body. Therefore, it is important for drug-like molecules to have a limited number of Hydrogen bond donors to ensure they can efficiently penetrate cell membranes and interact with their targets.What is the number of hydrogen bond donors in the molecule?
