Answer 1

A : CH3-CH2-CH=C(CH3)-CH2-CH3 + 3[O]⇒CH3-CH2-COOH +
+ CH3-CO-CH2-CH3
B : CH2=C(C2H5)-CH(CH3)-CH3 + 4[O] ⇒ CH3-CH2-CO-CH(CH3)-CH3 + +CO2 + H2O
raspuns: d)
7.                                      CxH2x + HBr ⇒CxH(2x+1)Br
 -mase molare :                      M                      M + 81
80·100/(M +81) = 52,98    M + 81 = 151     M = 70
14x = 70        x = 5     C5H10
A : CH2=CH-CH(CH3)-CH3   b)
