Question

Choose the incorrect statement.

• A. Propan-2-amine can be obtained by reacting acetoxime with $\text{Na} / \text{C}_2\text{H}_5\text{OH}$
• B. Fluorobenzene cannot be prepared from Benzenediazonium chloride by Sandmeyer's reaction because Fluorination of the Diazonium salt is highly endothermic in nature
• C. The decreasing order of basic strength of amines in aqueous solution is Ethanamine $>$ N,N-Dimethylaniline $>$ Benzenamine
• D. Aniline cannot be prepared by Phthalimide reaction

Hint:

Preparing fluorobenzene from a diazonium salt is always achieved via the Balz-Schiemann Reaction ($\text{HBF}_4$ addition followed by heating). Sandmeyer's chemistry fails here due to the instability of copper(I) fluoride catalysts, making statement (B) incorrect.

Answer 1

The Correct Option is B
