Answer 1

Ответ:

Объяснение:C2H4+ HCI->C2H5CI

C2H5CI +KNO2->C2H5NO2 +KCI

C2H5NO2+HNO2->C2H4(NO2)2 +H2

C2H4(NO2)2+6H2->C2H4(NH2)2 +4H2O

Answer 2

The series of chemical reactions you've provided involves the transformation of ethylene (C2H4) into diethylamine (C2H5(NH2)2). Let's break down the reactions step by step:

1. C2H4 → C2H5Cl: This is an example of a substitution reaction where ethylene (C2H4) reacts with hydrogen chloride (HCl) to form ethyl chloride (C2H5Cl): C2H4 + HCl → C2H5Cl

2. C2H5Cl → C2H5NO2: This reaction involves the substitution of a chlorine atom in ethyl chloride with a nitro group (NO2). This can be achieved through a nucleophilic substitution reaction, typically using sodium nitrite (NaNO2) and an acid: C2H5Cl + NaNO2 + HCl → C2H5NO2 + NaCl + H2O

3. C2H5NO2 → C2H4(NO2): In this step, nitroethane (C2H5NO2) is converted back into nitroethylene (C2H4(NO2)) by removing an alcohol group (-OH) from the nitroethane molecule. This reaction can be accomplished through various methods, such as heating: C2H5NO2 → C2H4(NO2) + H2O

4. C2H4(NO2) → C2H5(NH2)2: Finally, nitroethylene (C2H4(NO2)) can be reduced to diethylamine (C2H5(NH2)2) by adding reducing agents like hydrogen gas (H2) and a suitable catalyst: C2H4(NO2) + 3H2 → C2H5(NH2)2 + 2H2O

So, starting with ethylene (C2H4), you can follow these steps to obtain diethylamine (C2H5(NH2)2) through a series of chemical reactions. Each step involves specific reagents and conditions, but this is a general outline of the process.
