AI Thread Summary
Cycloalkanes typically do not react with bromine in the presence of CHCl3 because they primarily consist of single carbon-carbon bonds. While bromine can react with alkanes through a free radical mechanism, this process is less straightforward and requires high energy to initiate. The reaction is significantly slower compared to reactions involving alkenes or chlorine. Smaller, unstable cycloalkanes may exhibit some reactivity, but the overall reaction rate remains low. Understanding these dynamics is crucial for predicting the behavior of cycloalkanes in chemical reactions.

Homework Statement


according to my book, cycloalkane has no reaction with bromine when it is put into bromine in present of CHCCL3 ... why? as i know , the cycloalkane can undergo susbtituition with bromine . am i right?

Cycloalkanes have single bonds between carbon atoms. Bromine does not react with alkanes.
 
Actually it does, through the free radical mechanism. But it is not as easy as the double bond reaction, as it requires initialization through a high energy photon.

Hmm...I think its possible with the smaller unstable cycloalkanes, right?
 
All alkanes are capable of reacting this way. The reaction is much, much slower than the reaction with chlorine.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
