Alkenes show _ isomerism
Correct answer: C. Both geometrical and structural
- A. Only structural
- B. Only geometrical
- C. Both geometrical and structural
- D. Neither geometrical nor structural
Explanation
Alkenes exhibit both geometrical and structural isomerism. Geometrical isomerism arises from different groups attached to the carbon atoms on either side of the double bond. Structural isomerism occurs due to differences in the arrangement of atoms in the carbon skeleton. Option A is incorrect because alkenes exhibit both types of isomerism. Option B is incorrect as alkenes do not show only geometrical isomerism. Option D is incorrect as alkenes do exhibit both geometrical and structural isomerism.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
