Acetophenone

Vedclass · Answer

(C) The nitrosonium ion $(NO^{+})$ is an electrophile. The rate of reaction with an electrophile in electrophilic aromatic substitution depends on the electron density of the benzene ring. Electron-donating groups increase the rate,while electron-withdrawing groups decrease it.$1$. $Anisole$ $(-OCH_3)$: The $-OCH_3$ group has a strong $+M$ effect,which significantly increases the electron density of the ring,making it the most reactive.$2$. $Benzene$: This is the reference compound.$3$. $tert-Butylbenzene$ $(-C(CH_3)_3)$: The alkyl group has a $+I$ effect,which slightly increases the electron density,making it more reactive than benzene.$4$. $Acetophenone$ $(-COCH_3)$: The $-COCH_3$ group has both $-M$ and $-I$ effects,which strongly withdraw electrons from the ring,making it the least reactive.Therefore,$Acetophenone$ is the slowest to react with $NO^{+}$.

Which of the following compounds is the slowest to react with nitrosonium ion $(NO^{+})$?
