The major product Z formed in the following sequence of reactions is : [figure] (X = monochlorinated product)
- C2H5-N=N-OH
- C2H5OH
- C2H5NO2
- C2H5NH2
Answer
(2) C2H5OH
Solution
C2H6 Cl2, UV light C2H5Cl (X, free-radical substitution)
C2H5Cl NH3 C2H5NH2 (Y, ammonolysis)
As per NCERT, primary aliphatic amines react with nitrous acid (NaNO2 + HCl) to form unstable aliphatic diazonium salts, which give alcohols with evolution of N2:
C2H5NH2 NaNO2 + HCl [C2H5N2+Cl-] H2O C2H5OH + N2 + HCl
∴ Z = C2H5OH
Answer: (2)
