In case of nitration of benzene
WebIf we use the nitration of benzene as a reference, we can assign the rate of reaction at one of the carbons to be 1.0. Since there are six equivalent carbons in benzene, the total rate would be 6.0. WebTHE NITRATION OF BENZENE. This page gives you the facts and a simple, uncluttered mechanism for the electrophilic substitution reaction between benzene and a mixture of concentrated nitric acid and concentrated sulphuric acid. If you want the nitration mechanism explained to you in detail, there is a link at the bottom of the page.

WebWhy chloro benzene undergoes nitration about 30 times slower than benzene? It is less attractive for electrophiles, and so the reaction is slower. Since chlorine is an electron withdrawing group, so it withdraws electron from aromatic ring. As a result of which the electron density of the aromatic ring decreases and deactivates the ring. WebNitration of Benzene Mechanism: Addition reactions of arenes The delocalisation of electrons (also called aromatic stabilisation) in arenes is the main reason why arenes predominantly undergo substitution reactions over addition reactions In substitution reactions, the aromaticity is restored
WebThe nitration of benzene is a reaction that involves the substitution of a nitro group (-NO2) for a hydrogen atom on a benzene ring. The conditions required for this reaction are: … Webpossible when reaction on substituted benzenes occur, the isomers include ortho, meta, and para. Nitration at the meta position is optimal because of the partial charges residing at the ortho and para positions to repel the positively charged nitronium ion. Experimental Procedure: 6 mL of concentrated sulfuric acid was transferred into a 125-mL Erlenmeyer …
WebA solution of 1- (bromomethyl)-4- (trifluoromethyl)benzene (3.6 g, 15 mmol) in DMSO (5 mL) was then added dropwise over 10 min. When the addition was complete, the resulting mixture was stirred at room temperature for an additional 1 h. The mixture was quenched by the addition of water (200 mL).
WebCh12: Aromatic nitration. Overall transformation : Ar - H to Ar- NO 2. Reagent : for benzene, HNO 3 in H 2 SO 4 / heat. Electrophilic species : the nitronium ion ( i.e. NO 2+) formed by the loss of water from the nitric acid. MECHANISM FOR NITRATION OF BENZENE. Step 1: An acid / base reaction.
