Question

Se consumă acclaşi volum de soluție de K2Cr2O7, (H') la oxidarea:
1.2-pentenei 2.izobutenei;
3. 2-metil-1-pentenei; 3.2,3dimetil-2-butenei.​

Answer 1

1.

C-C=C-C-C + 4[O] --> C-COOH + HOOC-C-C

2.

C=C(C)-C + 4[O] --> CO2 + H2O + O=C(C)-C

3.

C=C(C)-C-C-C + 4[O] --> CO2 + H2O + O=C(C)-C-C-C

4.

C-C(C)=C(C)-C + 2[O] --> 2C-C(C)=O

=>

1, 2 si 3 consuma aceasi cantitate de agent oxidant

=> corecta A
