Alkene has ...... hydrogen atom less than the corresponding saturated hydrocarbons
Correct answer: A. Two
- A. Two
- B. Three
- C. Four
- D. Zero
Explanation
Alkenes have two fewer hydrogen atoms compared to the corresponding saturated hydrocarbons (alkanes) due to the presence of a carbon-carbon double bond. This double bond replaces two hydrogen atoms in the alkane structure. Therefore, the correct answer is Option A: Two. Options B, C, and D are incorrect because they do not reflect the specific difference in hydrogen atoms between alkenes and alkanes.

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.
