Whenever hydrogen bonding is involved in molecular recognition, the possibility of a proton transfer from the donor to the acceptor arises. In most cases the pK a of the donor is far enough above the pK a of the conjugate acid of the acceptor for it to be clear that no proton transfer will occur. Ho
