To convert m-ethylaniline to m-ethylfluorobenzene, it should be treated with nitrous acid followed by _____________.
1 answer:
Answer:
Explanation:
In this reaction, we must exchange the amino group () for a fluorine atom (
). Also, the first step in this reaction is the addition of nitrous acid.
We must remember that the amino group in the presence of nitrous acid produces a diazonium salt. The group is a very good leaving group and many benzene derivatives can be produced from this intermediate (see figure 1).
If what we want is to bond a fluorine atom we must use to be able to produce m-ethylfluorobenzene (see figure 2).
I hope it helps!

Time unit conversion
1 year = 365 days
1 day = 24 hours
1 hour = 3600 s

The limiting reagent will be Al
<h3>What are limiting reagents?</h3>They are reagents that limit the quantity of products that are formed in reactions.
From the equation of the reaction:
The mole ratio of Al to O2 is 4:3.
With 2 moles of Al and 2 moles of O2, Al becomes limiting while O2 is in excess.
With 2 moles of O2, the amount of Al required should be:
2 x 4/3 = 2.67 moles.
With 2 moles of Al, the amount of O2 required should be:
2 x 3/4 = 1.5 moles
Thus, O2 is in excess by 0.5 moles.
