Question

CaC2--C2H2--C6H6--C6H5NO2--C6H5NH2осуществите цепочку превращенийпомогите пожалуйста)))

Answer 1

CaC2+2H2O=Ca(OH)2+C2H2
3C2H2=C6H6 над знаком равно ставим С
C6H6+HNO3=C6H5NO2+H2O над знаком равно ставим H2SO4(к)
С6H5NO2+3H2=C6H5NH2+2H2O над знаком равно ставим Ni

Answer 2

Chain of Transformations: CaC2 -> C2H2 -> C6H6 -> C6H5NO2 -> C6H5NH2

1. CaC2 (Calcium Carbide) to C2H2 (Acetylene): - Calcium carbide (CaC2) can react with water (H2O) to produce acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2).

2. C2H2 (Acetylene) to C6H6 (Benzene): - Acetylene (C2H2) can undergo a process called cyclization, where it forms a ring structure to produce benzene (C6H6).

3. C6H6 (Benzene) to C6H5NO2 (Nitrobenzene): - Benzene (C6H6) can be nitrated by reacting with a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4) to produce nitrobenzene (C6H5NO2).

4. C6H5NO2 (Nitrobenzene) to C6H5NH2 (Aniline): - Nitrobenzene (C6H5NO2) can be reduced by using a reducing agent, such as iron and hydrochloric acid (Fe/HCl), to produce aniline (C6H5NH2).
