Which of the following compounds react most readily with Br2(g)?a)C2H2...
The compound that reacts most readily with Br(g) is C3H6. Here's why:
Explanation:
When a compound reacts with Br(g), it undergoes a substitution reaction called bromination. In this reaction, a Br atom replaces a hydrogen atom in the compound. The reactivity of a compound towards bromination depends on its structure and the stability of the resulting product.
Comparing the compounds:
Let's compare the given compounds and analyze their structures to determine which one is most reactive towards bromination.
a) C2H2:
C2H2 is an alkyne with a triple bond between two carbon atoms. This triple bond is very strong and stable, making it difficult for Br(g) to break it and substitute a hydrogen atom. Therefore, C2H2 is less reactive towards bromination.
b) C3H6:
C3H6 is an alkene with a double bond between two carbon atoms. The double bond is weaker and less stable than a triple bond. Therefore, it is easier for Br(g) to break the double bond and substitute a hydrogen atom. This makes C3H6 more reactive towards bromination compared to C2H2.
c) C2H4:
C2H4 is also an alkene with a double bond between two carbon atoms, similar to C3H6. It has the same structure as C3H6, but it has fewer carbon atoms. Since the number of carbon atoms does not significantly affect the reactivity towards bromination, C2H4 is also reactive towards bromination, but less reactive compared to C3H6.
d) C4H10:
C4H10 is an alkane with only single bonds between carbon atoms. Alkanes are generally less reactive towards bromination because the single bonds are strong and stable. Breaking a single bond to substitute a hydrogen atom is more difficult for Br(g) compared to breaking a double or triple bond. Therefore, C4H10 is the least reactive towards bromination among the given compounds.
Conclusion:
Based on the structural analysis and the stability of the bonds, C3H6 is the most reactive compound towards bromination among the given options.

Community Answer
Which of the following compounds react most readily with Br2(g)?a)C2H2...
The reactivity of a compound with Br(g) (Bromine gas) depends on the type of carbon-carbon bonds present in the compound. Compounds with double or triple bonds react more readily than those with single bonds because they have a higher electron density, which is more attractive to the electrophilic bromine.
Reactivity of Given Compounds:
C2H2: This compound has a triple bond between the two carbon atoms, which gives it a high electron density. However, the bond is also very strong, which makes the reaction slower.
C3H6: This compound has a double bond, which gives it a high electron density and makes it more reactive than compounds with single bonds. The double bond is weaker than the triple bond in C2H2, which makes the reaction faster.
C2H4: This compound has a double bond like C3H6. While it would also react readily with Br(g), the reaction would not be as fast as with C3H6 because C2H4 has fewer carbon atoms, and therefore less electron density.
C4H10: This compound only has single bonds, which makes it the least reactive of the four options.
In conclusion,C3H6 reacts most readily with Br(g) because it has a good balance of high electron density due to its double bond and faster reaction rate due to the bond's relative weakness. This makes it more attractive to the electrophilic bromine and allows the reaction to proceed more quickly.
