Answer 4

Reactions of Substitution and Addition

1) CH4 + Cl2 → - The reaction of methane (CH4) with chlorine (Cl2) results in the substitution of hydrogen atoms in methane with chlorine atoms. This is a typical example of a substitution reaction in organic chemistry. - This reaction can be represented as: `CH4 + Cl2 → CH3Cl + HCl` - The chlorine atom replaces one of the hydrogen atoms in methane, forming methyl chloride (CH3Cl) and hydrogen chloride (HCl) as products. This is a substitution reaction where chlorine substitutes for hydrogen in methane .

2) C2H2 + Cl2 → - The reaction of acetylene (C2H2) with chlorine (Cl2) results in the addition of chlorine atoms to the carbon-carbon triple bond in acetylene. This is a typical example of an addition reaction in organic chemistry. - This reaction can be represented as: `C2H2 + Cl2 → C2H2Cl2` - The chlorine atoms add across the carbon-carbon triple bond in acetylene, forming 1,2-dichloroethene (C2H2Cl2) as the product. This is an addition reaction where chlorine adds to the carbon-carbon triple bond in acetylene .

3) CH3COONa + HCl → - The reaction of sodium acetate (CH3COONa) with hydrochloric acid (HCl) results in the substitution of the sodium ion in sodium acetate with the hydrogen ion from hydrochloric acid. This is a typical example of a substitution reaction in inorganic chemistry. - This reaction can be represented as: `CH3COONa + HCl → CH3COOH + NaCl` - The hydrogen ion from hydrochloric acid replaces the sodium ion in sodium acetate, forming acetic acid (CH3COOH) and sodium chloride (NaCl) as products. This is a substitution reaction where the hydrogen ion substitutes for the sodium ion in sodium acetate .

4) C6H6 + Br2 → - The reaction of benzene (C6H6) with bromine (Br2) results in the addition of bromine atoms to the benzene ring. This is a typical example of an addition reaction in organic chemistry. - This reaction can be represented as: `C6H6 + Br2 → C6H5Br + HBr` - The bromine atoms add to the benzene ring, forming bromobenzene (C6H5Br) and hydrogen bromide (HBr) as products. This is an addition reaction where bromine adds to the benzene ring in benzene .

5) H2SO4 + Zn → - The reaction of sulfuric acid (H2SO4) with zinc (Zn) results in the displacement of hydrogen from sulfuric acid by zinc. This is a typical example of a displacement reaction in inorganic chemistry. - This reaction can be represented as: `H2SO4 + Zn → ZnSO4 + H2` - The zinc displaces the hydrogen from sulfuric acid, forming zinc sulfate (ZnSO4) and hydrogen gas (H2) as products. This is a displacement reaction where zinc displaces hydrogen from sulfuric acid .

6) H2SO4 + CuO → - The reaction of sulfuric acid (H2SO4) with copper(II
