a) (1) dehydrogenation reaction:
CH3-CH3 —–> CH2 = CH2 + H2.
(2) hydration in the presence of H2SO4:
CH2 = CH2 + H2O —–> CH3-CH2-OH.
(3) reaction with hydrogen bromide in the presence of H2SO4:
CH3-CH2-OH + HBr —–> CH3-CH2-Br + H2O.
b) (1) dehydration, t = 140 ° C, H2SO4:
CH3-CH2-OH —–> CH2 = CH2 + H2O.
CH2 = CH2 + H2 —–> CH3-CH3.
CH3-CH3 + Br2 —–> CH3-CH2-Br + HBr.
