A hydrogen bond acceptor can be defined as a component of a hydrogen bond that does not contribute to the bridging hydrogen atom. This could be an atom, ion or a molecule that is capable of forming a hydrogen bond by accepting a hydrogen ion from a donor molecule. In other words, the hydrogen bond acceptor attracts the positively charged hydrogen atom of the donor molecule towards itself, forming the hydrogen bond. Some examples of hydrogen bond acceptors are oxygen (in water molecules), nitrogen (in ammonia molecules), sulfur, and fluorine. Therefore, understanding the concept of hydrogen bond acceptors is crucial in explaining the properties and interactions of chemicals in various fields of science.What is the count of hydrogen bond acceptors present in the molecule?
