Can Aldehydes Form Hydrogen Bonds
On whether an aldehyde can form a hydrogen bond
An aldehyde is also a class of organic compounds. Its structure contains a carbonyl group, with one end connected to hydrogen and the other end to a hydrocarbon group. On whether an aldehyde can form a hydrogen bond.
The formation of a hydrogen bond requires an atom with a large electronegativity (such as fluorine, oxygen, and nitrogen), and is connected to a hydrogen atom. At the same time, there is another atom with a large electronegativity that can act as a hydrogen receptor. In the aldehyde, the oxygen of the carbonyl group has a certain electronegativity. However, the hydrogen of the aldehyde is connected to carbon, and the electronegativity of the carbon is relatively small, and the connected hydrogen cannot have the strong positive electricity required to form a hydrogen bond.
Therefore, it is difficult to form a typical hydrogen bond between the However, the carbonyl oxygen of an aldehyde can be used as a hydrogen receptor. If there are substances with active hydrogen in the system, such as alcohol and water, the carbonyl oxygen of an aldehyde can form a hydrogen bond with its hydrogen. For example, when an aldehyde is mixed with water, the carbonyl oxygen of an aldehyde can form a hydrogen bond with the hydrogen of a water molecule, which also affects the solubility of an aldehyde in water.
In summary, it is difficult to form a hydrogen bond between an aldehyde itself, but in a specific system, an aldehyde carbonyl oxygen can be used as a hydrogen receptor to form a hydrogen bond with a substance containing active hydrogen.
