Phenyl benzoate nitration
WebThe ring of phenyl benzoate with highest electron density would undergo nitration more easily as the para position on the ring is more favorable due to steric strain . 5. Which is nitrated faster, toluene or phenol? Explain. a. Phenol is nitrated much faster than toluene due to the presence of an -OH group. WebA. a protecting group to prevent over-nitration B. a source of electrophiles to activate the aromatic ring for nitration C. a catalyst to convert nitrate to nitrite ion D. a temporary electrophile followed by its replacement with nitronium ion E. a catalyst to convert nitrate to nitronium ion Kindly explain your answer. arrow_forward

Selectivity can be a challenge in nitrations because as a rule more than one compound may result but only one is desired, so alternative products act as contaminants or are simply wasted. Accordingly, it is desirable to design syntheses with suitable selectivity; for example, by controlling the reaction conditions, fluorenone can be selectively trinitrated or tetranitrated. The substituents on aromatic rings affect the rate of this electrophilic aromatic substitution.
