Concept explainers
(a)
Interpretation: The highlighted carbon atom of the given compound that absorbs farther downfield is to be identified.
Concept introduction: Depending upon the electron density or the concentration of electron around carbon, the chemical shift values of carbon varies relative to the reference signal. The terms, upfield and downfield expresses the relative location of signals. The meaning of upfield is to the right and of downfield is to the left.

- match the correspoding molecule to IR spectrum. ( only on molecule per spectrum)arrow_forwardDraw the structure of each compound next to its matching spectrum. Mark peaks on the spectra that helped you pick that compound.arrow_forwardWhich of the highlighted carbon atoms in each attached molecule absorbs farther downfield ?arrow_forward
- can they distinguish by HNMR spectrum ? and if yes How many peak they show in HNMR spectrum ?if not , why ?arrow_forwardWhich proton in each pair absorbs further downfield?arrow_forwardYou may draw the structures in either Kekule, condensed, or mixed format initially. In the tables draw them as skeletal structures. Attach the sheet of paper with your DEPT spectra at the end of this packet before turning your packet in.arrow_forward
- Answer part b. Please ensure its legiblearrow_forwardMatch each IR spectrum to the molecule from a pool of structures below eachspectrumarrow_forwardCan we say because of the one i circle with red in the paper , can we say we have aromatic overtone on both that region with benzoic acid ir spectum thank uarrow_forward
