    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations

    3. The attempt at a solution

    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.
