Question

Addition reactions and substitution reactions are types of organic reactions. Which type of reaction is shown by :
(i) ethane​

Answer 1

Ethane shows substitution reaction. When ethane reacts with chlorine it forms hexachloroethane. ​
\(C_{2}H_{6}+Cl_{2}\rightarrow C_{2}H_{5}Cl+ HCl\)
Chloroethane
\(C_{2}H_{5}Cl +Cl_{2} \rightarrow C_{2}H_{4}Cl_{2}+ HCl\)
Dichloroethane
\(C_{2}H_{4}Cl_{2} +Cl_{2} \rightarrow C_{2}H_{3}Cl_{3}+ HCl\)
Trichloroethane
\(C_{2}H_{3}Cl_{3} +Cl_{2} \rightarrow C_{2}H_{2}Cl_{4}+ HCl\)
Tetrachloroethane
\(C_{2}H_{2}Cl_{4} +Cl_{2} \rightarrow C_{2}HCl_{5}+ HCl\)
Pentachloro ethane
\(C_{2}HCl_{5} +Cl_{2} \rightarrow C_{2}Cl_{6}+ HCl\)
Hexachloroethane​
