Question

ПОМОГИТЕ ПОЖАЛУЙСТА С ХИМИЕЙ!!! 10 КЛАСС!!! ДАЮ 95 БАЛЛОВ!!! Задание: Осуществите цепочку превращений, укажите условия протекания реакций, назовите вещества по цепочке: C2H2-----> C2H6-----> C2H5Cl

Answer 1

C2H2 + 2H2 = C2H6 (гидратация)(етин + водород = етан)
C2H6 + Cl2 = C2H5Cl + HCl (етан + хлор2 = хлоретан)

Answer 2

Chain of Transformations and Conditions for Reactions:

To convert C2H2 to C2H6 and then to C2H5Cl, we need to go through a series of chemical reactions. Here is the chain of transformations along with the conditions for each reaction:

1. Conversion of C2H2 to C2H6: - Reaction: Hydrogenation - Conditions: Catalytic hydrogenation is typically carried out in the presence of a catalyst, such as palladium (Pd) or platinum (Pt), at elevated temperatures and pressures. - Equation: C2H2 + H2 → C2H6

2. Conversion of C2H6 to C2H5Cl: - Reaction: Chlorination - Conditions: Chlorination reactions are typically carried out in the presence of a chlorine (Cl2) source and a radical initiator, such as light or heat. - Equation: C2H6 + Cl2 → C2H5Cl + HCl

Substances Involved in the Chain:

The substances involved in the chain of transformations are as follows:

1. C2H2: Acetylene - Acetylene is a hydrocarbon with the chemical formula C2H2. It is a colorless gas that is commonly used in welding and as a starting material for various organic compounds.

2. C2H6: Ethane - Ethane is a saturated hydrocarbon with the chemical formula C2H6. It is a colorless gas that is commonly used as a fuel and as a starting material for the production of ethylene.

3. C2H5Cl: Chloroethane - Chloroethane is an organic compound with the chemical formula C2H5Cl. It is a colorless liquid that is used as a solvent and as an intermediate in the production of other chemicals.

Please note that the conditions and equations provided are general representations of the reactions involved. The actual reaction conditions may vary depending on the specific reaction setup and the desired reaction conditions.
