Which could not be directly prepared from 4-bromobenzenediazonium ion?A. BromobenzenB. 1,4-dibromobenzeneC. 4-bromoacetophenoneD. 4-bromofluorobenzene

Which could not be directly prepared from 4-bromobenzenediazonium ion?

1.	Which could not be directly prepared from 4-bromobenzenediazonium ion?A. BromobenzenB. 1,4-dibromobenzeneC. 4-bromoacetophenoneD. 4-bromofluorobenzene
Answer» Correct Answer - C Diazo group cannot be replaced directly by aceto `(CH_3CO-)` group, remaining all groups `(-CN,-Br` and `-F)` can be brought directly. Hence, among the given, 4-bromoacetophenone cannot be prepared directly from corresponding diazonium salt.
