Question

C5H12-C2H6-C2H6-C2H4-C2H4CL2

Answer 1

СH₃-CH₂-CH₂-CH₂-CH₃ (t°)⇒ CH₃-CH₃ + CH₃-CH=CH₂

CH₃-CH₃ (Cr₂O₃;t⁰) ⇒ CH₂=CH₂

CH₂=CH₂ + Cl₂ ⇒ Cl-CH₂-CH₂-Cl

Answer 2

The chemical formula "C5H12-C2H6-C2H6-C2H4-C2H4Cl2" represents a hydrocarbon chain with several different molecules. Let's break down the formula:

1. C5H12: This represents pentane, which is an alkane with five carbon atoms and 12 hydrogen atoms in the molecular formula.

2. C2H6: This represents ethane, which is an alkane with two carbon atoms and six hydrogen atoms in the molecular formula.

3. C2H6: Another ethane molecule.

4. C2H4: This represents ethene (ethylene), which is an alkene with two carbon atoms and four hydrogen atoms in the molecular formula.

5. C2H4Cl2: This represents 1,2-dichloroethane, which is a dihaloalkane with two carbon atoms, four hydrogen atoms, and two chlorine atoms in the molecular formula.

To summarize, the chemical formula "C5H12-C2H6-C2H6-C2H4-C2H4Cl2" refers to a chain of hydrocarbon compounds connected in the following order: pentane (C5H12) - ethane (C2H6) - ethane (C2H6) - ethene (C2H4) - 1,2-dichloroethane (C2H4Cl2).
