Question

CaC2-C2H2-C2H4-C2H5Cl-C2H4Cl2

Answer 1

CaC2->C2H2->C2H4->C2H5Cl->C2H4Cl2

CaC2+2 H2O = Ca(OH)2+C2H2

C2H2+H2↑ = C2H4

C2H4+HCl = C2H5Cl

C2H5CL+CL2 = C2H4CL2+HCL

Answer 2

The sequence "CaC2-C2H2-C2H4-C2H5Cl-C2H4Cl2" appears to represent a series of chemical compounds formed through different reactions. Let's go through each compound step by step:

1. CaC2: Calcium carbide is a chemical compound composed of calcium and carbon, represented by the formula CaC2.

2. C2H2: Acetylene, also known as ethyne, is a hydrocarbon gas with the chemical formula C2H2. It is often produced by the reaction of calcium carbide (CaC2) with water (H2O).

3. C2H4: Ethylene, also known as ethene, is a hydrocarbon gas with the chemical formula C2H4. It is an unsaturated hydrocarbon and an important industrial chemical.

4. C2H5Cl: Chloroethane is a chemical compound with the formula C2H5Cl. It is an alkyl halide and belongs to the class of organic compounds known as haloalkanes.

5. C2H4Cl2: Dichloroethane is a chemical compound with the formula C2H4Cl2. It is a type of chlorinated hydrocarbon and exists in two isomeric forms: 1,1-dichloroethane and 1,2-dichloroethane.

The sequence represents a series of chemical transformations, starting with the formation of calcium carbide (CaC2) and proceeding to produce acetylene (C2H2) through the reaction with water. Ethylene (C2H4) is then formed, and further chlorination reactions lead to the production of chloroethane (C2H5Cl) and dichloroethane (C2H4Cl2).
