Cyclohexane can be converted into benzene by catalytic dehydrogenation in the presence of oxides of D block for ex V2O5, Cr2O3 etc. Cyclohexane when heated at 6000C in presence of Al2O3-Cr2O3 gives benzene.
Free radical bromination of cyclohexane:
Cyclohexane + Br2 + heat ---> Bromocyclohexane + HBr(g)
CH3-CH3 + Br2 ---> CH3CH2Br + KOH(alc)-----> CH2=CH2 + HBr(in presence of CCl4)-----> CH2Br-CH2Br +KOH(alc)-----> CH2=CHBr
Ethene can be convert to bromoethene by reacting with hydrogen-bromide, which is called hydroalogenation
CH2=CH2 + HBr -----> CH3- CH2Br

Ethyne is most reactive where as ethane is least.

Pyrolysis to convert the ethane to ethene. The add Alkaline Pottasium permanganate solution.
Both ethene and ethane contain two carbons. Ethene has a double bond between its two carbons while ethane has a single bond. Because of this, ethane contains six hydrogen atoms, but ethene only contains four.

You are trying to reduce ethane to ethene, I am guessing. That is a very hard reaction to do... probably you will have to do a free radical halogenation on ethane to form 1-chloroethane, followed by an E2 reaction with t-butoxide or some other bulky base to form ethene. Since ethane and ethene are both gases and cheaply available from petroleum cracking, this reaction really isn't worth doing.
