Count Hydrogen Atoms in Skeletal Structure
On how to count the hydrogen atoms in the skeleton structure
If you want to know the number of hydrogen atoms in the skeleton structure, you need to understand the method. Where carbon is, it is tetravalent. In the skeleton structure, the carbons are connected by bonds, and where there is no obvious bond, they are all attached to hydrogen.
Looking at the skeleton, if the carbon is only connected to one other carbon, the remaining trivalent must be accounted for by hydrogen; if it is connected to two carbons, the remaining divalent is bonded to hydrogen; when it is connected to three carbons, only the monovalent is related to hydrogen; if it is connected to four carbons, there is no hydrogen connected to it.
Such as hydrocarbons, the chain-like skeleton of alkanes, the first and last carbons, each connected with trihydrogens; the intercarbon connected In cycloalkanes, the carbon is connected to dihydrogens, but at the corner of the ring, it is regarded as the same as dicarbons, and each is attached to dihydrogens.
In the genus of alkenyne, at the double bond of carbon and carbon in the alkenyl, each is connected to a diyl group. If it is hydrogen, the number of hydrogen is also calculated according to its price.
In this way, according to the valence state of carbon, the skeleton structure and the number of hydrogen atoms can be obtained in detail.
