бутан---изобутан--2-метилбутанол-2 - - - 2 - метилбутен-1

1) CH3-CH2-CH2-CH3 (AlCl3) = CH3-CH (CH3) - CH3

2) CH3-CH (CH3) - CH3+Cl2 (t) = CH3-CCl (CH3) - CH3+HCl

3) CH3-CCl (CH3) - CH3+KOH=CH3-COH (CH3) - CH3+KCl

CH3-COH (CH3) - CH3+Cl2 (t) = CH3-COH (CH3) - CH2Cl+HCl

CH3-COH (CH3) - CH2Cl+2Na+Cl-CH3=CH3-COH (CH3) - CH2-CH3+2NaCl

CH3-COH (CH3) - CH2-CH3 (t, H+) = CH2=C (CH3) - CH2-CH3+H2O
