it doesn’t take place on a racetrack with cars that were designed for racing‚ but instead it occurs off road and the race cars have been replaced by buggies‚ rally cars‚ SUVs‚ and muscle cars. Nitro Tip numbero uno is to always take full advantage of nitro boost. As you’re probably already aware‚ nitro enables you to go faster for short periods of time and can be restored by picking up power-ups as you race. But the trick is to wait until you have 3 bars‚ then wait until it’s red‚ this means you

acid. This nitration is a type of electrophilic aromatic substitution. A strongly charged electrophile‚ in this case a nitro group‚ replaces a proton on the aromatic ring. Aromatic compounds undergo substitution instead of addition to maintain resonance. The substituent on the benzene ring determines where the electrophile will add. Electron withdrawing substituents‚ like nitro group‚ withdraw electrons due to induction and direct position of the carbocation through resonance to add electrophile

substitution reaction‚ where nitro (NO2) group is being substituted for a hydrogen on an aromatic compound. This is achieved by the formation of the nitronium ion by protonation of nitric acid from sulfuric acid. The zirconium ion is a strong electrophile and can react with aromatic compound such as Methyl benzoate to form an arenium ion intermediate. The arenium ion is then depronated to reform the aromatic ring and yield the final product with the newly attached nitro group. Reaction:

these planes‚ one should at least have some experience with the electric types which provide some basic skills which are meant for novices. It is difficult to handle the new planes as they are complex and powerful. These models are often confused with nitro RC helicopters‚ but their engines are entirely different. These helicopters use regular gasoline that is mixed with two-cycle engine oil. Even though they have some similarities‚ the main difference is based on the ignition system that determines

has the weakest conjugate base? ANS: p-nitrophenol 16. Refer to Exhibit 17-2. How do you account for the difference in acidity between meta and para-nitrophenol? ANS: In m-nitrophenol‚ the inductive effect of the electron-withdrawing nitro group helps to stabilize the negative charge on oxygen.

with the hydroxyl group and the nitro group single bonded to the aromatic ring. This occurs at the pH of 5. At this point the aromatic compound is colorless and is in the ultraviolet range. However‚ as the pH begins to increase the hydroxyl group deprotonates‚ leaving the oxygen with a negative 1 charge. The molecule compensates for the negative charge by conforming to a more stable resonance structure. The structure now has the oxygen and the nitrogen for the nitro group double bonded to the ring
