Решить цепочку превращений: ch3-ch2-ch2oh -h2so4,180c-> x1 -hcl-> x2 -naoh.h2o-> x3 -h2so4,180c-> x1 -kmno4,h2o,0c-> x4

1) CH3-CH2-CH2OH -H2SO4,180C-> CH3-CH=CH2 + H2O
2) CH3-CH=CH2 + HCl -> CH3-CHCl-CH3
3) CH3-CHCl-CH3 + NaOH -H2O-> CH3-CHOH-CH3 + NaCl
4) CH3-CHOH-CH3 -H2SO4,180C-> CH3-CH=CH2 + H2O
5) 3CH3-CH=CH2 + 2KMnO4 + 4H2O -> 3CH3-CHOH-CH2OH + 2MnO2 + 2KOH
