The reactant that will be the best reactant for a nucleophilic aromatic substitution is NO₂- NO₂. The correct option is b.
<h3>What is nucleophilic
aromatic substitution?</h3>
Nucleophilic aromatic substitution is a substitution process of nucleophile substance is substituted by halides in an aromatic ring. Aromatic compounds contain this type of substitution.
In option b, the compound is the one nitroxide group substituted by halogen, that is fluorine. The fluorine group is substituted in these given aromatic compounds.
Thus, the correct option is b, NO₂- NO₂.

Answer:
Explanation:
<u><em>Given :</em></u>
Mass in grams = m = 42 g
Molar Mass = M = 12
<u><em>Required:</em></u>
No. of moles = n = ?
<u><em>Formula :</em></u>
m = m / M
<u><em>Solution:</em></u>
n = 42 / 12
n = 3.5 moles
30.962
34500
28512
31860
answer:
7.49 x 105 mm
0.45 miles
885 yards
34500 inches
reason:
I converted all the measurements to inches.
First, I multiplied 7.49x105 to get 786.45mm
Then, I divided it by 25.4 to get about 30.92 inches
Next, I converted 0.45 miles to inches by multiplying it by 63,360 to get 28,512 inches
For the yards, I took 885 and multiplied it by 36 to get 31,860 inches
Since the last one was already in inches, all I needed to do was put them in order from least to greatest
Answer : The conversion used is, 
Explanation :
The conversion used :
For example : To convert 10 feet into inches.
From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be,
