The aromaticity of the compound is lost in this important step. Water‚ acting as the Lewis base‚ removes a proton from the carbon bonded to the nitro group‚ an aromatic benzyl structure is created again: nitroacetanilide; thus ending the nitration reaction (1). Next‚ an acid-catalyzed hydrolysis reaction occurs to remove the acyl group. The nitroacetanilide receives a proton from the sulfuric acid and the double bonded oxygen becomes positively charged. A sp3 hybridized carbon compound is formed
