You are correct. Typically to obtain a useful yield of the monochlorinated product you would have to have an extremely large excess of cyclohexane relative to chlorine and then separate out the product.

Wouldn’t overhalogenation be a problem, since the C-H-bonds in monochlorocyclohexane are (with exception of the C-Cl) bond very similar in terms of bond strength? Even if the product of the first halogenation may be less reactive than the starting material (which it barely is, presumably), the extreme reactivity of the halogen radicals would easily substitute the remaining hydrogens.

Sorry for the long question and thank you in advance!

Thanks a lot!

How can I determine whether a reaction will proceed via a radical- or polar-mediated pathway?

Come on, that shouldn’t take too much time to find the answer to.

Neutral means that it bears no formal charge. Non-polar means that, to a good approximation, the molecule doesn’t have a significant dipole moment.

They are neutral. In most polar reactions there is an activation barrier for forming a charged species such as a carbocation which can be reduced through solvation with a polar solvent. Not the case here.

Free radical carbon atoms are electron deficient and they are stabilized by electron releasing groups next to it.
But why aren’t they stabilized by solvation?
