Question

am nevoie de ajutor, la exercitiile 2,3,4... va rog mult...

Answer 1

2)
A - 1-butanal
B - 2-butanonă
C - C6H5-CO-CH3
D - C6H5-CH=O
E - 1,2-propandial
F - CH3-CO-CH3
3) CnH2n-2 + H2O = CnH2nO
%O = mO/m CnH2nO * 100
22,22 = 16/(14n+16) * 100
1600 = 311n + 355,52
n = 4
C4H8O
CH3-CH2-CH2-CH=O 1 - BUTANAL
CH3-CH2-CO-CH3 2-BUTANONĂ
CH3-CH(CH3)-CH=O 2-METIL-1-PROPANAL

4)A'     CH3          H
                   C=C
             H            CH=O
B' CH3-CH2-CO-CH2-CH3
C' CH3-CH2-CHCH3-CH=O
D' CH3-CH2-CH=O
E' CH3-CH2-CO-CH3
