Consequently, hydroxyl (-OH) and amine (-NH2) groups aren’t present in aprotic solvents and will’t build hydrogen bonds. Protic and aprotic solvents both of those have the potential to dissolve ions. These solvents don’t comprise much acidic hydrogen, hence there isn’t a significant launch of hydrogen ions. Dielectric consistent values for polar aprotic solvents are modest or reasonable. These solvents Have a very moderate diploma of polarity.
