 :) 

1.)  1-bromo-2-cyclohexylethane -----------> vinylcyclohexane
       Dehydrohalogenation using bulky base in DMSO solvent . Using NaOEt in EtOH as solvent will
       give substitution product rather than elimination one.

2.)  vinylcyclohexane ---------------> 1-cyclohexylethane-1,2-diol
       Hydroxylation using following reagents
         (i) Cold aqueous alkaline KMnO4
                         OR
        (ii) OsO4 followed by hydrolysis
