Understanding the Reaction
The reaction provided is between ethylene (CH2=CH2) and bromine (Br2) in aqueous solution, leading to the formation of 1,2-dibromoethane (BrCH2-CH2Br). This process exemplifies a specific type of chemical reaction.
What is an Addition Reaction?
- An addition reaction occurs when two or more molecules combine to form a single product.
- In this case, the double bond in ethylene is broken, allowing bromine to add across the carbon atoms.
Why is it Not Other Types of Reactions?
- Substitution Reaction: This involves replacing an atom or group in a molecule with another atom or group. Here, no atoms are replaced; instead, new atoms are added.
- Hydrogenation Reaction: This specifically involves the addition of hydrogen (H2) to a compound, typically unsaturated hydrocarbons. In this reaction, bromine is added instead of hydrogen.
- Combustion Reaction: This type involves the reaction of a substance with oxygen to produce energy, usually in the form of heat and light. The reaction presented does not involve combustion.
Conclusion
Thus, the reaction between ethylene and bromine is a clear example of an addition reaction, where the addition of bromine to the carbon-carbon double bond results in the formation of a saturated compound. This is why option 'C' is the correct answer.
