Answer 1

Ответ:

1. внутримолекулярная дегидратация - Б. C3H7OH → C3H6   + H2O

2. частичное окисление - А. C2H5OH + CuO → CH3COH + Cu + H2O

3. межмолекулярная дегидратация  - Г. 2CH3OH + 2Na → 2CH3ONa + H2

4. полное окисление - В. С2Н5ОН + 3О2 → 2СО2 + 3Н2О

Answer 2

Matching Reactions with Schemes

To match the reactions (A-D) with the corresponding reaction schemes (1-4), let's analyze each reaction and its equation:

1. Intramolecular Dehydration: This reaction involves the removal of a water molecule from within a single molecule. - Equation: 2CH3OH → CH3OCH3 + H2O - Scheme: D

2. Partial Oxidation: This reaction involves the partial oxidation of a compound. - Equation: C3H7OH → C3H6 + H2O - Scheme: B

3. Intermolecular Dehydration: This reaction involves the removal of a water molecule between two different molecules. - Equation: C2H5OH + CuO → CH3COH + Cu + H2O - Scheme: A

4. Complete Oxidation: This reaction involves the complete oxidation of a compound. - Equation: 2CH3OH + 2Na → 2CH3ONa + H2 - Scheme: C

Therefore, the matching between the reactions and schemes is as follows: 1. Intramolecular Dehydration: Scheme D 2. Partial Oxidation: Scheme B 3. Intermolecular Dehydration: Scheme A 4. Complete Oxidation: Scheme C
