Question

Помогите решить цепочку))) С3Н6->C3H6Cl2->C3H6-C3H8->C3H7Br->C614->C6H5CH3->2,4, 6-тринитротолуол

Answer 1

C3H6 + Cl2 = C3H6Cl2
???
2C3H7Br + 2Na = C6H14 + 2NaBr
C6H14 -> C6H6 + 4H2
C6H6  + CH3Cl = C6H5CH3 + HCl
C6H5CH3 + 3HNO3 = 2,4, 6-тринитротолуол + 3H2O

Answer 2

Chemical Reactions in the Given Chain

Let's break down the chemical reactions in the given chain:

1. C3H6 -> C3H6Cl2: - In this reaction, C3H6 (propene) reacts with chlorine gas (Cl2) to form C3H6Cl2 (1,2-dichloropropane). - The reaction is an example of an addition reaction, where the chlorine atoms add to the carbon-carbon double bond in propene.

2. C3H6Cl2 -> C3H6-C3H8: - In this reaction, C3H6Cl2 (1,2-dichloropropane) undergoes a dehydrohalogenation reaction to form a mixture of C3H6 (propene) and C3H8 (propane). - The reaction involves the elimination of a hydrogen chloride (HCl) molecule from 1,2-dichloropropane, resulting in the formation of a double bond in propene and the release of HCl.

3. C3H6-C3H8 -> C3H7Br: - In this reaction, a bromine (Br2) molecule adds across the double bond of propene (C3H6) to form 2-bromopropane (C3H7Br). - The reaction is an example of an addition reaction, where the bromine atom adds to one of the carbon atoms in the double bond.

4. C3H7Br -> C6H14: - In this reaction, C3H7Br (2-bromopropane) undergoes a substitution reaction with excess sodium (Na) metal to form C6H14 (hexane). - The reaction is known as a Wurtz reaction, where the alkyl halide (C3H7Br) reacts with sodium metal to form a new carbon-carbon bond and sodium bromide (NaBr) as a byproduct.

5. C6H14 -> C6H5CH3: - In this reaction, C6H14 (hexane) undergoes a catalytic reforming process to form C6H5CH3 (toluene). - The reaction involves the rearrangement of carbon atoms in hexane to form a methyl group attached to a benzene ring.

6. C6H5CH3 -> 2,4,6-trinitrotoluene: - In this reaction, C6H5CH3 (toluene) undergoes nitration with a mixture of nitric acid (HNO3) and sulfuric acid (H2SO4) to form 2,4,6-trinitrotoluene (TNT). - The reaction involves the substitution of three nitro groups (-NO2) onto the benzene ring of toluene.

Conclusion

To summarize the chemical reactions in the given chain: C3H6 -> C3H6Cl2 -> C3H6-C3H8 -> C3H7Br -> C6H14 -> C6H5CH3 -> 2,4,6-trinitrotoluene
