Which formula represents an unsaturated hydrocarbon?
a. C3H6
b. C3H8
Is the answer B? Thanks! :)
Yes, you are correct! The formula C3H8 represents an unsaturated hydrocarbon.
Now, let me explain how you can determine whether a hydrocarbon is unsaturated or not.
Unsaturated hydrocarbons are those that contain at least one double or triple bond between carbon atoms. These bonds allow the hydrocarbon to have fewer hydrogen atoms compared to the corresponding saturated hydrocarbon with the same number of carbon atoms.
In the given options, the formula C3H6 corresponds to propene, which contains one double bond between two carbon atoms. This makes it an unsaturated hydrocarbon.
On the other hand, the formula C3H8 corresponds to propane, which contains only single bonds between carbon atoms. Therefore, it is a saturated hydrocarbon.
So you correctly identified that the answer is option a. C3H6. Well done!
Yes, the answer is B. C3H8 represents an unsaturated hydrocarbon. Unsaturated hydrocarbons are characterized by the presence of one or more carbon-carbon double or triple bonds. In this case, C3H8 represents propane, which is an example of a saturated hydrocarbon.
Here is how you know.
The general formula for a saturated hydrocarbon (alkanes) is
CnH2n+2.
For unsaturated hydrocarbons(alkenes) it is
CnH2n.
For unsaturated hydrocarbons (alkynes) it is
CnH2n-2
