Question

CH4->C-> CH4->CH3Br->C2H6->C2H4->C2H5Cl​

Answer 1

Ответ:

СН4 + Br2 -> CH3-Br + HBr

CH3-Br + 2Na + Br-CH3 -> CH3-CH3. + 2NaBr

CH3-CH3 -> CH2=CH2 +H2

CH2=CH2 + HCl -> CH3-CH2-Cl

Answer 2

The given sequence represents a series of chemical reactions starting with methane (CH4) and proceeding through several intermediate compounds to ultimately form ethyl chloride (C2H5Cl). Let's break down each step in the reaction sequence:

1. CH4: Methane is the initial compound.
2. C: The reaction is not explicitly specified here, but it suggests the formation of carbon as an intermediate product.
3. CH4: Methane appears again in the sequence, indicating the possible involvement of another molecule of methane.
4. CH3Br: This represents the substitution reaction between methane (CH4) and bromine (Br2), resulting in the formation of methyl bromide (CH3Br).
5. C2H6: The reaction is not specified, but it indicates the formation of ethane (C2H6) as an intermediate.
6. C2H4: Again, the reaction is not explicitly mentioned, but it implies the formation of ethene (C2H4).
7. C2H5Cl: Finally, the reaction ends with the formation of ethyl chloride (C2H5Cl), suggesting the substitution reaction between ethene (C2H4) and chlorine (Cl2).

It's important to note that this sequence represents a simplified version of the reactions, and in actual chemical reactions, there may be specific conditions, catalysts, or steps involved to achieve the desired products.
