Make up the reaction equation: С2Н4 → С2Н2 → C6 H6 → С6Н5Сl → С6Н5OH → С6Н5ONa.

Make up the reaction equation: С2Н4 → С2Н2 → C6 H6 → С6Н5Сl → С6Н5OH → С6Н5ONa. СН4 → СН3Br → С2Н6 → С2Н4 → С2Н5OH → СН3 СОН.

C2H4 = C2H2 + H2 – dehydrogenation reaction, ethylene was formed

3C2H2 = C6H6- trimerization reaction, benzene is obtained

C6H6 + Cl2 = (FeCl3, t) = C6H5Cl + HCl- qualitative reaction to benzene

C6H5Cl + H2O = C6H5OH + HCl- qualitative reaction for benzenes, smells of bitter almonds, chlorination reaction, halogenation

C6H5OH + NaOH = C6H5ONa + H2O- sodium phenolate is formed.

CH4 + Br2 = CH3Br + HBr- alkane enters into a substitution reaction with halogen – Br2

2CH3Br + 2Na = C2H6 + 2NaBr

C2H6 = (catalyst) = C2H4 – dehydrogenation reaction

C2H4 + H2O = C2H5OH- the water addition reaction is called hydration

C2H5OH + CuO = CH3COH + Cu + H2O- the color does not change, but a smell appears that differs from the smell of ethanol.
