WebThe word ‘protic’ refers to a proton or a Hydrogen atom or ion. Thus, a protic solvent has a hydrogen atom present in it. This hydrogen atom is such that it can be easily released to be available to solutes via hydrogen bonding. Hence, the hydrogen atom should be bonded to an electronegative atom like Oxygen, Nitrogen, Fluorine, etc.
