About the composition of Graphite molecular structure components
Do you mean Graphite molecular structure components? Assembling is to draw the structure of the molecule, just use a sphere and a small stick to overlap it. This model is an intuitive representation of the spatial structure of molecules, including bond lengths and bond angles. Mainly spatial conformation.
You can also rotate the bond to create different spatial configurations to observe the stability of the molecule. The polar bond is the connection of two different atoms, and the non-polar bond is the connection of two identical atoms. For example, h-cl is a polar bond. cl-cl is a non-polar bond, the definition is not like this, but it is just memorized like this in junior high school.
Generally, the tetrahedral structure is a special regular tetrahedron, such as methane, the bond angle is 28 degrees, and the carbon element is formed by sp3 hybrid orbitals. There is no orbital hybridization of the nitrogen element in the ammonia molecule, and there is an irregular tetrahedron composed of a lone electron pair and 3 hydrogen atoms. This requires additional memory. It is recommended not to be confused with the regular tetrahedron.
According to Graphite molecular structure components, four covalent bonds can be formed, and hydrogen atom, fluorine atom, and chlorine atom can form one covalent bond, so judge based on this. The molecule is an organic substance. The carbon atoms in the organic molecule form 4 covalent bonds. From the hydrogen atom on the left, it is inferred that the first carbon-carbon bond is a carbon-carbon triple bond, the second carbon-carbon bond is a single bond, and the third It is a triple bond. In the same way, it can be deduced that ① is a carbon-carbon triple bond, ② is a carbon-carbon single bond, and ③ the carbon connected to it should be a triple bond.
