A ---------> B
-H2

KMnO4
B --------------> CH3COOH + CH3COCH3
H2SO4

Substanta A este:

a) neopentan

b) izopentan

c) n-pentan

d) izobutan

e) n-butan

sper sa se inteleaga

Answer 1

CH3COOH + CH3-CO-CH3 <= CH3-C=C(CH3)2

CH3-CH=C(CH3)-CH3 = 2-metil-2-butena = B

CH3-CH=C(CH3)-CH3 <=_t>650_ CH3-CH2-CH(CH3)-CH3 = A

=> A = 2-metilbutan sau izopentan => b)
