a) CnH2n-2 + H2O = CnH2nO
4+1+1 = 6 atomi de C => n = 6 => C6H12O
CH3
A: CH3-C-CH2-CH=O 3,3-dimetil-1-butenal
CH3
b) M C6H12O = 100 g/mol
100 g A........1 mol O
x g A............5 moli O
x = 500 g A
c) CH3
B: CH3-C-CO-CH3 2,2-dimetil-2-butanona
CH3

d) * CH3
D: O=CH-CH-CH-CH3 2,3-dimetil-1-butanal
CH3
12.5
A - 3-metil-5-penten-1-al
B - 1-buten-4-onă
C - E-3-penten-2-onă
D - cis-3-penten-1-al
