Does CH3OH Form Hydrogen Bonds
On whether methanol can form hydrogen bonds
Methanol ($CH_3OH $), the properties of this substance are related to whether hydrogen bonds can be formed, which is one of the main topics of chemical exploration.
The hydrogen bond of the husband is a genus of non-chemical bonds, but it has a great influence on the physical and chemical properties of the substance. Its formation requires specific conditions. The hydrogen atom must be covalently bonded with the atom with large electronegativity and small radius (such as nitrogen, oxygen, fluorine), and the hydrogen atom needs to interact with another atom with large electronegativity and containing lone pairs of electrons.
The structure of methanol, in which the hydrogen atom and the oxygen atom are covalently bonded. The oxygen atom is very electronegative, and the hydrogen atom connected to the oxygen in the methanol, the electron cloud is biased towards the oxygen atom, causing the hydrogen atom to be partially positively charged. The oxygen atom of the methanol molecule has a lone pair of electrons. In this way, a partially positively charged hydrogen atom in a methanol molecule can attract each other with an oxygen atom containing a lone pair of electrons in another methanol molecule, and then form a hydrogen bond.
Try to extrapolate from common sense, if methanol cannot form hydrogen bonds, its boiling point and solubility should be the same as many similar organic compounds that cannot form hydrogen bonds. In fact, methanol has a relatively high boiling point and excellent solubility in water, which is a strong evidence for the existence of hydrogen bonds.
In summary, methanol ($CH_3OH $) can indeed form hydrogen bonds. This conclusion has important guiding significance in many fields of chemical research, such as the exploration of solution properties and the design of organic synthesis.
