Choose the incorrect statement.
Options
- AAniline cannot be prepared by Phthalimide reaction
- BPropan–2–amine can be obtained by reacting acetoxime with Na / C₂ H₅ OH
- CThe decreasing order of basic strength of amines in aqueous solution is Ethanamine > N,N–Dimethylaniline > Ben
- DFluorobenzene cannot be prepared from Benzenediazonium chloride by Sandmeyer's reaction because Fluorination o
Correct answer
D. Fluorobenzene cannot be prepared from Benzenediazonium chloride by Sandmeyer's reaction because Fluorination o
Step-by-step solution
Gabriel phthalimide synthesis is used for the preparation of primary aliphatic amines. Aniline cannot be prepared by this method because aryl halides do not undergo nucleophilic substitution with the anion formed by phthalimide. Statement A is correct. Acetoxime is (CH₃)₂C=NOH . Reduction of acetoxime with Na / C₂H₅OH yields propan-2-amine, (CH₃)₂CHNH₂ . Statement B is correct. Aliphatic amines are more basic than aromatic amines. Among aromatic amines, the +I effect of two methyl groups in N,N-dimethylaniline incr
