The compound that ontains the most deactivated aromatic ring is the one called Nitrogen dioxide also knwon as NO2. Let me explain a little bit more about the aromatic rings. These rings are simple aromatics, or arenes, that consist of a conjugated planar ring system. Nitrogen generally is a simple aromatic ring that can be heterocyclic because containsnon-carbon ring atoms. The rings of the nitrogen can be separated into basic aromatic rings and that is why this ompound is also refered as a deactivated aromatic ring.
Answer:
5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Explanation:
Given data:
Moles of NO formed = ?
Moles of N₂ reacts = 2.86 mol
Solution:
Chemical equation:
N₂ + O₂ → 2NO
Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.
N₂ : NO
1 : 2
2.86 : 2/1×2.86 = 5.72 mol
So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
