CxH2x + HOH = CxH(2x+1)O
nC = nCO2 = 264/44 = 6
nH = 1/2·nH2O = 1/2 ·108/18 = 12
a) C6H12
b) H2C= C(CH3)-CH2-CH2-CH3 ; H3C-CH=C(CH3)-CH2-CH3 ;
c) H2C=C(CH2CH3) -CH2-CH3 +[O] = CH3-CH2-CO-CH2-CH3 +CO2 +H2O
A : H3C-CH2-(HO)C(CH3)-CH2-CH3
d) M alchena = 84g/mol n = 0,1moli
teoretic : n alcool = 0,1 moli M = 102g/mol m = 10,2g
m practic = 0,9·10,2 = 9,18g
