How To Draw A Hydrogen Bond
The method of drawing hydrogen bonds
If you want to draw hydrogen bonds, be clear. Hydrogen bonds are the weak interactions between a hydrogen atom and an atom with a large electronegativity and a small radius (such as nitrogen, oxygen, fluorine, etc.) after bonding with a covalent bond, and another atom with a large electronegativity.
To draw a hydrogen bond, you first need to confirm the group where the atom with hydrogen and a large electronegativity is located. For example, in water, hydrogen is connected to oxygen, and hydrogen bonds can be formed between two water molecules. When drawing, use lines to represent covalent bonds, connecting hydrogen to a connected electronegative large atom, such as H-O. Then, the hydrogen bond is shown in dashed lines, leading from the hydrogen of a molecule to the electronegative atom of another molecule, such as H · · O. The dotted line should be slightly longer than the solid line of the covalent bond to show the characteristics of its weak interaction.
If the hydrogen bond between organic molecules, such as alcohols, is drawn, the same principle is followed. The molecular structure of the first time is to determine the position of the hydroxyl group (-OH), and the hydrogen of the hydroxyl group and the oxygen of the adjacent molecular hydroxyl group can form a hydrogen bond. According to the above method of using the solid line to express the covalent and the dashed line to indicate the hydrogen bond. The drawing must be accurate, and the positions of each atom and the ratio of the bond angle should be in line with the chemical reality, so that the hydrogen bond can be clearly drawn, which can help the analysis and study of the chemical structure.
