Question

Етаналь = А = Етен = Б = Бутан ​

Answer 1

Из этаналя получаем этен в две реакции.
1)CH3CHO + H2 --> C2H5OH
2) C2H5OH --> C2H4 + H2O (t=110-120°c, катализатор H2SO4)
из этена получем бутан тоже в две реакции
1)C2H4 + HCl --> CH3-CH2Cl
2)Реакция Вюрца
CH3-CH2Cl + 2Na + CH3-CH2Cl --> CH3-CH2-CH2-CH3 + 2 NaCl

Answer 2

It seems like you're trying to create a chemical equation using the names of some hydrocarbons. However, the names you've provided are a bit mixed up. Let me clarify the correct names and then explain their relationship:

1. Ethane: Ethane is a simple hydrocarbon with the chemical formula C2H6.

2. Ethene (or Ethylene): Ethene is another hydrocarbon with the chemical formula C2H4. It is an unsaturated hydrocarbon and is commonly known as "ethylene."

3. Butane: Butane is a hydrocarbon with the chemical formula C4H10.

Now, let's discuss their relationship:

1. Ethane (C2H6) is a saturated hydrocarbon, meaning it has only single bonds between carbon atoms. It is composed of two carbon atoms and six hydrogen atoms.

2. Ethene (C2H4) is an unsaturated hydrocarbon because it contains a double bond between its two carbon atoms. It consists of two carbon atoms and four hydrogen atoms.

3. Butane (C4H10) is also a saturated hydrocarbon, like ethane, but it contains four carbon atoms and ten hydrogen atoms.

The correct chemical equation representing the relationship you provided would be:

Ethane (C2H6) = Ethene (C2H4) = Butane (C4H10)

This equation shows that ethane can undergo a chemical reaction to form ethene, and ethene can further react to produce butane. The reaction would involve breaking or forming carbon-carbon bonds and rearranging hydrogen atoms.
