Interpretation:
The total number of hydrogen atoms present in the given molecule has to be identified.
Concept Introduction:
Organic compounds are the important basis of life. They include gasoline, coal, dyes, and clothing fibers etc. The compounds that are obtained from living organisms are termed as organic compounds and those obtained from the earth are known as inorganic compounds. Organic compounds are found in earth also apart from living organisms. All the organic compounds contain the element carbon. Urea was synthesized in the laboratory which is an organic compound.
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

Answer to Problem 2.27EP
The total number of hydrogen atoms present is 14.
Explanation of Solution
Cyclolkanes are saturated hydrocarbons that contain only single bonds between carbon atoms with ring structure. The general molecular formula for cycloalkane is
Carbon atoms are present at the intersection and at the end points. The above structure has six intersections and one end point. Therefore, there is a total of seven carbon atoms. The total number of hydrogen atoms can be found by substituting in the general molecular formula as shown below,
The total number of hydrogen atoms that will be present in the given cycloalkane is found to be fourteen.

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.
Alkanes are a class of saturated hydrocarbons that do not contain a ring of carbon atoms but a chain of carbon atoms with carbon‑carbon single bonds. The general molecular formula for alkanes is
Alkenes and cycloalkenes are a class of unsaturated hydrocarbons that contain at least one double bond in its structure. The general molecular formula for alkene with one double bond is
(b)

Answer to Problem 2.27EP
The total number of hydrogen atoms present is 12.
Explanation of Solution
Cycloalkenes are unsaturated hydrocarbons that contain at least one double bond between carbon atoms with ring structure. The general molecular formula for cycloalkene with one double bond is
Carbon atoms are present at the intersection and at the end points. The above structure has six intersections and one end point. Therefore, there is a total of seven carbon atoms. The total number of hydrogen atoms can be found by substituting in the general molecular formula as shown below,
The total number of hydrogen atoms that will be present in the given cycloalkene is found to be twelve.
