Question

Здійснити перетворення :CAC2-C2H2-C2H4-C2H5CL-C4H10

Answer 1

CaC2+2H2O=C2H2+Ca(OH)2
C2H2+H2=C2H4
C2H4+HCl=C2H5Cl
2C2H5Cl+2Na=C4H10+2NaCl

Answer 2

Transformation of CAC2-C2H2-C2H4-C2H5CL-C4H10

The given sequence of compounds can be transformed as follows:

1. CAC2 to C2H2: - CAC2 is calcium carbide, which can react with water to produce acetylene gas (C2H2). - The reaction equation is: CAC2 + 2H2O → C2H2 + Ca(OH)2.

2. C2H2 to C2H4: - Acetylene gas (C2H2) can undergo a process called hydrogenation to produce ethylene gas (C2H4). - The reaction equation is: C2H2 + H2 → C2H4.

3. C2H4 to C2H5Cl: - Ethylene gas (C2H4) can react with chlorine gas (Cl2) to produce ethyl chloride (C2H5Cl). - The reaction equation is: C2H4 + Cl2 → C2H5Cl.

4. C2H5Cl to C4H10: - Ethyl chloride (C2H5Cl) can undergo a reaction called dehydrochlorination to produce butane (C4H10) and hydrogen chloride (HCl). - The reaction equation is: C2H5Cl + C4H8 → C4H10 + HCl.

Therefore, the transformation of the given compounds is as follows: CAC2 → C2H2 → C2H4 → C2H5Cl → C4H10.
