Question

Care din alchenele de mai jos respecta schema de reactie:
A+H2O->B-H2O->A
a)1 butena
b)izobutena
c)2 butena
d)propena

Answer 1

Identificăm fiecare caz
CH2=CH-CH2-CH3 + H2O = CH3-CHOH-CH2-CH3 - H2O = CH3-CH=CH-CH3
CH2=C(CH3)2 + H2O = (CH3)3C-OH - H2O = CH2=C(CH3)2
CH3-CH=CH-CH3 + H2O = CH3-CHOH-CH2-CH3 - H2O = CH3-CH=CH-CH3
CH2=CH-CH3 + H2O = CH3-CHOH-CH3 - H2O = CH3-CH=CH2
Variantele corecte sunt b, c, d
