Question

Складіть рівняння реакцій за схемою. Дайте назви речовинам: ch4>c2h2>ch3coh>ch3cooh>ch3coo-ch3>ch3-oh>co2

Answer 1

Ответ:

1) 2СH4→ С2H2+3H2( при t = 1800С)

2) С2H2+ HOH → СH3СНО (среда кислая, катализатор соли ртути

3) СH3СНО+2Сu(OH)2→ СH3COOН+Cu2O↓+H2O(качественная р-я на альдегиды)

4) СH3COOН+CH3OH<==>  СH3COO-CH3+H2O(p-я протекает в кислой среде,  при t)

Answer 2

Equation and Substance Names:

The given chemical reaction scheme can be represented by the following equations:

1. CH4 → C2H2 2. C2H2 → CH3COH 3. CH3COH → CH3COOH 4. CH3COOH → CH3COO-CH3 5. CH3COO-CH3 → CH3-OH 6. CH3-OH → CO2

The substances involved in the reactions are:

1. CH4: Methane 2. C2H2: Acetylene 3. CH3COH: Ethanol 4. CH3COOH: Acetic acid 5. CH3COO-CH3: Methyl acetate 6. CH3-OH: Methanol 7. CO2: Carbon dioxide

Please note that the given reaction scheme represents a series of chemical reactions where one substance is converted into another through a series of steps.
