Which structure is a valid representation of a hydrocarbon molecule?
Answer:
The formula for acyclic saturated hydrocarbons (i.e., alkanes) is CnH2n+2. The most general form of saturated hydrocarbons is CnH2n+2(1-r), where r is the number of rings. Those with exactly one ring are the cycloalkanes.
Explanation:
Answer:
An example of a hydrocarbon molecule structure is shown in the image below.
Explanation:
Hydrocarbons are organic compounds specifically made up of carbon and hydrogen atoms. The molecular structure consists of a framework of carbon atoms to which the hydrogen atoms are attached. The carbon atom chains can be linear or branched, and open or closed.
