Question

Complete the reaction: c6h5n2cl 1) hbf4 2) nano2/o3, ∆

Answer 1

Hello Dear,

● Answer with explanation -

# Step I -

When benzene diazonium chloride is treated with HBF4, fluorobenzene is formed.

C6H5-N2Cl + HBF4 → C6H5-F + N2 + HCl + BF3

# Step II -

Fluorobenzene on reaction with NaNO2/O3 gives nitrobenzene.

C6H5-F + NaNO2 + ∆ → C6H5-NO2 + NaF

# Overall reaction -

Overall reaction can be written as -

C6H5-N2Cl (HBF4 + NaNO2/O3) → C6H5-NO2

Hope this is useful. Keep asking questions..
