The major product Z formed in the following sequence of reactions is : C ₂ H ₆ [ UV light ] Cl ₂ X NH ₃ Y [( monochlorinated product )] (i) NaNO ₂/ HCl (ii) H ₂ O Z
Options
- AC ₂ H ₅ NO ₂
- BC ₂ H ₅-N=N- OH
- CC ₂ H ₅ OH
- DC ₂ H ₅ NH ₂
Correct answer
C. C ₂ H ₅ OH
Step-by-step solution
Ethane undergoes free radical halogenation with chlorine in the presence of UV light to form ethyl chloride (X). C ₂ H ₆ + Cl ₂ UV light C ₂ H ₅ Cl (X) Ethyl chloride reacts with ammonia via nucleophilic substitution to form ethylamine (Y). C ₂ H ₅ Cl + NH ₃ C ₂ H ₅ NH ₂ (Y) Ethylamine, being a primary aliphatic amine, reacts with nitrous acid ( NaNO ₂ + HCl ) to form an unstable aliphatic diazonium salt, which decomposes to yield a carbocation. The carbocation reacts with water to form ethanol (Z). C ₂ H ₅ NH ₂ Na
