Concept Introduction:
Hydrocarbons are the organic compounds that contain only hydrogen and carbon atoms. Hydrocarbon derivatives are the one in which the compounds contain hydrogen and carbon atoms along with one or more additional elements. The additional elements that can be present in hydrocarbon derivatives are oxygen, nitrogen, sulphur, chlorine, bromine etc.
Hydrocarbons are further classified into two categories. They are saturated hydrocarbons and
Saturated hydrocarbons are
Alkane has general molecular formula as CnH2n+2. Alkene in which one double is present has general molecular formula as CnH2n. Alkyne in which one triple bond is present has the general molecular formula as CnH2n-2. Cycloalkanes have the general molecular formula as CnH2n. Cycloalkenes in which one double bond is present have the general molecular formula as CnH2n-2.
(a)

Answer to Problem 13.12EP
Given molecular formula belongs to an alkene with one double bond.
Explanation of Solution
Given molecular formula is C4H8. Considering the general molecular formula the value of “n” is 4. The total number of hydrogen atoms present in the given molecular formula is 8. This is twice the number of carbon atoms. Hence, the general molecular formula of the given compound can be deduced as CnH2n. This is a general molecular formula of alkene with one double bond.
The given molecular formula is found to be that for an alkene containing one double bond.
(b)
Interpretation:
The given molecular formula belongs to alkene with one double bond, or a cycloalkene with one double bond has to be indicated.

Hydrocarbon derivatives are the one in which the compounds contain hydrogen and carbon atoms along with one or more additional elements. The additional elements that can be present in hydrocarbon derivatives are oxygen, nitrogen, sulphur, chlorine, bromine etc.
Hydrocarbons are further classified into two categories. They are saturated hydrocarbons and unsaturated hydrocarbons. The hydrocarbons that contain single bonds between carbon atoms in the entire molecule is known as saturated hydrocarbon. The hydrocarbons that contain atleast one double or triple bond between two carbon atoms in the entire molecule is known as unsaturated hydrocarbon.
Saturated hydrocarbons are alkanes. Unsaturated hydrocarbons are alkene, alkyne and aromatic hydrocarbons.

Answer to Problem 13.12EP
Given molecular formula belongs to a cycloalkene with one double bond.
Explanation of Solution
Given molecular formula is C5H8. Considering the general molecular formula the value of “n” is 5. The total number of hydrogen atoms present in the given molecular formula is 8. This is two numbers less than the twice number of carbon atoms. Hence, the general molecular formula of the given compound can be deduced as CnH2n-2. This is a general molecular formula of cycloalkene with one double bond.
