How To Draw Hydrogen Bonding
On the Method of Drawing Hydrogen Bonds
If you want to draw hydrogen bonds, the first thing to understand is the rationale. Hydrogen bonds are non-chemical bonds, which are special interactions between molecules or within molecules. The formation must also have a polar molecule containing hydrogen. Hydrogen is connected to atoms with large electronegativity and small radius, such as nitrogen, oxygen, and fluorine. This hydrogen then has strong positive electricity and can be attracted by a weak force with atoms with large electronegativity in other molecules, which is a hydrogen bond.
When drawing, first confirm the molecular structure containing hydrogen bonds. Take water as an example. Hydrogen in water molecules is connected to oxygen, and oxygen is electronegative, and hydrogen is positively charged. Draw water molecules, where oxygen lives in the center, and hydrogen is separated on both sides. Hydrogen-oxygen covalent bonds are represented by solid lines.
Then show hydrogen bonds. Between adjacent water molecules, a dashed line connects the hydrogen of one water molecule and the oxygen of other water molecules. This dashed line is the hydrogen bond. Pay attention to the direction of the hydrogen bond, and it must point from the hydrogen to the atom with large electronegativity.
If you draw complex systems, such as hydrogen bonds in proteins or nucleic acids, follow this principle. First draw the molecular skeleton in detail, and clarify the positions of each atom, especially the atoms containing hydrogen and those with large electronegativity. Then according to the rules of hydrogen bond formation, connect the relevant atoms with dashed lines to clearly show the hydrogen bond network.
Drawing hydrogen bonds, the key is to be accurate, the structure should be clear, and the hydrogen bond orientation and position must be confirmed, so that this special interaction between molecules can be accurately depicted, which can help to study the properties and structures of matter.
