Chlorination and bromination of alkanes can be done mostly in the presence of:
Correct answer: D. All of these
- A. Diffused sunlight
- B. High temperature
- C. U.V light
- D. All of these
Explanation
The correct answer is Option D: All of these. The reason being that in all three cases (diffused sunlight, high temperature, and UV light), the common mechanism for halogenation of alkanes involves the formation of reactive halogen radicals. These radicals abstract hydrogen atoms from alkanes, leading to the formation of alkyl radicals, which further react with halogen molecules to form the final halogenated products.Options A, B, and C are incorrect because they each focus on one specific condition (diffused sunlight, high temperature, or UV light) rather than recognizing that all these sources of energy can initiate halogenation reactions in 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.
