| In a system of pure methanol, a dimer of methanol is formed. Along with the addition of water, the dimer's hydrogen bond is broken due to the formation of stronger hydrogen bond between water and methanol. The theoretically calculated value of hydrogen bond for the methanol dimer is N, less than that between water and methanol, which confirms the tendency of the H-bond formation between methanol and water. |
