Answer:
See the answer below
Explanation:
Organic molecules in the form of carbohydrates are created during photosynthesis or chemosynthesis and these processes cause carbon to be removed from the atmosphere or other environment into the biosphere - the living organisms of the ecosystem.
During photosynthesis, atmospheric carbon dioxide is fixed as carbohydrates into green plants in a two-stage process that requires sunlight energy and water. The entire process can be summarized as an equation below:
Instead of using water as a reactant, chemosynthetic organisms make use of high energy chemicals such as hydrogen sulfide to fix carbon dioxide in order to generate carbohydrates.
Both processes ensure that carbon dioxide moves from the environment into living organisms.
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.
