Question

va rog mult... urgent​

Answer 1

C = monoester etilic , pt ca provine din etanol (reactia 2) => R-COOC2H5 ,

R+12+16x2+29 = R+73 g/mol

=>

100% ............................ 31,37% O

R+73.............................. 32 g O

=> R = 29

=> R = CH3CH2-

=> C = C2H5COOC2H5 = propionatul

CH3CH2OH + [O] --KMnO4/H(+)--> CH3COOH (B)

CH3CH2COOH + HOC2H5 --H(+)--> CH3CH2COOC2H5 (C)
