Ochem terminology

can someone help me get what do you call it when br2 to a methylcyclopentane? is it mark/anti mark?

what about when you add Cl2 and CCl4 to an alkene? mark/anti
mark?

when is it when all the H's are replaced with halogens?

what does monochlorination means when added to methylcyclopentene? is it radical? Cl2/ HCl? or what?

define radical halogenation with an example please.

I am all confused with these terms

thanks

1. When adding Br2 to a methylcyclopentane, it adds to the tertiary carbon. It is called free radical bromination.

Markov doesn't come into play in this type of reaction because there is no H added. Markov simply means that IF and H is added, it will add to the carbon that already has more H's.

2. When you add Cl2 to an alkene, it is called Halogenation of an Alkene. or more specifically Chlorination of alkene. The CCl4 is just the solvent.

3. Monocholorination means one chlorine is added. It is the same thing as the first question but you just use chlorine. The general reaction is called Free radical halogenation.

4. Radical halogention means a radical is generated, which causes a sequence of other radicals being generated. This website will completely explain it http://www.absoluteastronomy.com/topics/Free_radical_halogenation

thanks,
what about this one?
when is it when all the H's are replaced with halogens?
