Question

Compusi organici izomeri (inclusiv stereoizomeri) C5H8O2 ce dau efervescenta cu NaHCO3 si decoloreaza Br2/CCl4 sunt in numar de
A. 8
B. 9
C. 10
D. 11
E. 12
Ce fel de compusi dau efervescenta cu NaHCO3?

Answer 1

acizi carboxilici nesaturati dau reactie efervescenta cu nahco3 si decoloreaza bromul

ch3-ch=ch-ch2-cooh 2
ch3-ch2-ch=ch-cooh 2
ch2=ch-ch2-ch2-cooh 1
h2c=c(ch3)-ch2-cooh 1
h3c-c(ch3)=ch-cooh 1
h3c-ch=c(ch3)-cooh 2
h2c=ch-ch(ch3)-cooh 1

10 compusi....poti sa mi confirmi te rog daca e bine?
