Answer:
See the attachment for the filled in chart.
Let me know if you need any other help:)
Explanation:
Part a
Pyridine is an aromatic heterocyclic compound and undergoes nucleophilic aromatic substitution reaction at 2 and 4 positions.
This is because, when a nucleophile attack pyridine at 2 and 4 positions, the anoin formed is stabilized. In the anion formed is tabilized by resonance and also negative charge is present at electronegative atom, nitrogen.
If the nucleophile attack at 3 position, the anion formed is not as stable as anions formed when nucleophile attach at 2 and 4 positions. This is because negative charge is not present at the nitrogen atom.
Part b:
Tautomers are structural isomers of each others formed by migration atom within the molecule. Tautomers exist in equilibrium with each other.
Tautomers of 2-Hydroxypyridine and 4-Hydroxypyrine are given in the attachment.
Question∵
Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?
Answer:
Hi, There! -Randp12- My Name Is jay I'm here to help! :)
<u><em>The correct answer is lower frequency.</em></u>
Explanation:
Information to Support My Answer :D
it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
Therefore for higher wavelength, the electromagnetic wave will also have lower frequency.
Hope this helps!
