Question

Viết PTHH khi cho các chất sau : Na,K,C2H5OH,CH3COOH,NaOH,Zn tác dụng với a. Rượu etylic b. Axit axetic

Answer 1

a, \(C_2H_5OH+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\)

\(C_2H_5OH+K\rightarrow C_2H_5OK+\dfrac{1}{2}H_2\)

\(C_2H_5OH+CH_3COOH⇌CH_3COOC_2H_5+H_2O\) (xt: H₂SO₄ đặc, t^o)

b, \(CH_3COOH+Na\rightarrow CH_3COONa+\dfrac{1}{2}H_2\)

\(CH_3COOH+K\rightarrow CH_3COOK+\dfrac{1}{2}H_2\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\) (xt: H₂SO₄ đặc, t^o)

\(CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O\)

\(2CH_3COOH+Zn\rightarrow\left(CH_3COO\right)_2Zn+H_2\)
