1. CH3-CHOH-CH2-CH3+HBr-->CH3-CHBr-CH2-CH3+H2O
2. 2CH2OH-CH2-CH3+Ba-->
(CH2O-CH2-CH3)2Ba+H2
3. CH2OH-CH(-CH3)-CH2-CH3+CuO-->CHO-CH(-CH3)-CH2-CH3+Cu+H2O
4. 3CH3-CHOH-CH3+K2Cr2O7+4H2SO4-->3CH3-C(=O)-CH3+Cr2(SO4)3+K2SO4+7H2O
5. CH3-C(-CH3)=CH-CH3+H2O-->CH3-COH(-CH3)-CH2-CH3

a) D(O2)=M(C3H7OH)/M(О2)=60г/моль/32г/моль=1,875
б) D(Н2)=M(C3H7OH)/M(H2)=60г/моль/2г/моль=30
в) D(возд.)=M(C3H7OH)/M(возд.)=60г/моль/29г/моль≈2,07
