WebDescription. Protic solvents are capable of hydrogen bonding because they contain at least one hydrogen atom connected directly to an electronegative atom (such as O-H or N-H bonds). Aprotic solvents contain no hydrogen atoms connected directly to an electronegative atom and they are not capable of hydrogen bonding. Example. Web5 mei 2016 · Protonation pattern strongly affects the properties of molecular systems. To determine protonation equilibria, proton solvation free energy, which is a central quantity in solution chemistry, needs to be known. In this study, proton affinities (PAs), electrostatic energies of solvation, and pKA values were computed in protic and aprotic solvents.

The given compound does not contain O-H bonds and cannot be regarded as a protic solvent. Hence, compound b is an aprotic solvent. c. The given compound does not possess O-H bonds and is not a protic solvent. Hence, compound c is an aprotic solvent. WebExamples of polar protic solvents are water (HOH), methanol (CH 3 OH), and acetic acid (CH 3 CO 2 H). Dipolar Aprotic Solvents. Here the key word is aprotic. In the context used here, aprotic describes a molecule that does not contain an O-H bond. Solvents in this class all contain a bond that has a large bond dipole. colocation marthe et marie
