Question

* Determina formula moleculara, formula structurala si denumirea acidului monocarboxilic saturat care are masa molara 60. ​.

Answer 1

Răspuns:

Formula moleclara: C2H4O2

Formula structurala: CH₃-COOH

Denumire: acid etanoic sau acid acetic

Explicație:

acid monocarboxilic saturat => formula generala:  $\boxed{C_n\ H_2_nO_2}$

μ=12n+2n+32=14n+32 g/mol

acidul monocarboxilic saturat are masa molara 60 => μ=60

DECI: 14n+32=60 => 14n=28 => n=2

Formula moleclara: C2H4O2

Formula structurala: CH₃-COOH

Denumire: acid etanoic sau acid acetic
