a) butan -> 1- chlorobutan -> 1- butanol -> buten
C4H1O + Cl2--hv--> CH3-CH2-CH2-CH2Cl + HCl
butan chlorobutan
CH3-CH2-CH2-CH2Cl+ NaOH--H2O--> CH3-CH2-CH2-CH2-OH+NaCl
1-butanol
CH3-CH2-CH2-CH2-OH ---Al2O3,T--> CH3-CH2-CH=CH2+ H2O
buten
b) 1- buten -> 2- butanol -> butanon
CH2=CH-CH2-CH3 +HOH --> CH3-CH-CH2-CH3 --> 2-butanol
1-buten I
OH
3CH3-CH-CH2-CH3 +K2Cr2O7 + 4H2SO4 -->3CH3-C-CH2-CH3 + K2SO4
I II +
OH O Cr2(SO4)

2-butanol butanon 7H2O
