Answer 2

reactii de obtinere de acetali si cetalii corespunzatori

R-CH=O + R-OH --> R-C(OH)-O-R = semiacetal

+ R'-OH --> R-C(-OR')-O-R acetal, deoarece a plecat de la aldehida

R2C=O + R-OH --> R2C(OH)-O-R = semicetal

+ R'-OH --> R2C(-OR')-O-R cetal, deoarece a plecat de la cetona

(CH3)2CH-CO-CH3 + C2H5-OH --H+--> (CH3)2CH-C(OH)(-O-C2H5)-CH3

+ C2H5-OH --H+--> (CH3)2CH-C(O-C2H5)(O-C2H5)-CH3

poza 2

(CH3)2CH-CH=O + CH3-OH --H+--> (CH3)2CH-C(OH)-O-CH3

+ CH3-OH --H+--> (CH3)2CH-C(O-CH3)-O-CH3
