Structure along with ¹H-NMR is shown below.
Signal for Hₐ; Based on multiplicity of of the peak, a
Singlet peak (the only singlet peak present in spectrum) at
2.2 ppm was assigned to Hₐ. As the methyl group in not coupling with any other proton so it gave a singlet peak.
Signal for Hb; Based on multiplicity of of the peak, a
Quartet peak (the only quartet peak present in spectrum) at
2.4 ppm was assigned to Hb. As the methylene group in coupling with methyl group having three protons so it gave a Quartet peak.
Signal for Hc; Based on multiplicity of of the peak, a
Triplet peak (the only triplet peak present in spectrum) at
1.1 ppm was assigned to Hc. As the methyle group in coupling with methylene group having two protons so it gave a Triplet peak.
Answer:
C) The most efficient fusion reactors would use heavier forms of hydrogen.
Explanation:
From the information presented to us in the question, the third sentence reveals that heavier forms of hydrogen produces larger amount of energy and most importantly reacts more efficiently when fusion occurs.
<em>In fact, the </em><u><em>heavy isotopes of hydrogen—deuterium and tritium—react more efficiently</em></u><em> with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei. </em>
Answer:
1. Na2SO4 + Ba(NO3)2 → NaNO3 + BaSO4
2. NaNO3 + NH4Cl → NaCl + NH4NO3
4. Sorry, I don't know
5. Refer to the attachment..
6. NaC2H3O2(aq) + AgNO3(aq) = NaNO3(aq) + AgC2H3O2

Answer:
D) All Of The Above
Explanation:
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.
Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.
