CH3-CH2-CH3 + 2Br2 = CH3-C(Br)2-CH3 + 2HBr
CH3-C(Br)2-CH3 + 2KOH = CH3-C≡CH + 2KBr + 2H2O
CH3-C≡CH + H2O = CH3-C(O)-CH3
CH3-C(O)-CH3 + H2 = CH3-CH(OH)CH3
CH3-CH2-CH3 + 2Br2 = CH3-C(Br)2-CH3 + 2HBr
CH3-C(Br)2-CH3 + 2KOH = CH3-C≡CH + 2KBr + 2H2O
CH3-C≡CH + H2O = CH3-C(O)-CH3
CH3-C(O)-CH3 + H2 = CH3-CH(OH)CH3
