a)
Interpretation:
A structure for ketone or aldehyde with the following descriptions is to be proposed.
C4H7ClO, IR: 1715 cm-1; 1HNMR: 1.62 δ (Rel.area=3.00), 2.33 δ (Rel.area=3.00), 4.32δ (Rel.area=1.00).
Concept introduction:
In 1HNMR the aldehyde protons absorb near 10 δ with a coupling constant , J = 3Hz. Hydrogens on the carbon next to aldehyde group absorb near 2.0-2.3 δ. Methyl ketones show a sharp three proton singlet near 2.1 δ.
To purpose:
A structure for ketone or aldehyde with the following descriptions.
C4H7ClO, IR: 1715 cm-1; 1HNMR: 1.62 δ (Rel.area=3.00), 2.33 δ (Rel.area=3.00), 4.32δ (Rel.area=1.00).
b)
Interpretation:
A structure for ketone or aldehyde with the following descriptions is to be proposed.
C7H14O, IR: 1710 cm-1; 1HNMR: 1.02 δ (Rel.area=4.50), 2.12 δ (Rel.area=1.50), 2.33δ (Rel.area=1.00).
Concept introduction:
Aldehydes and ketones show a strong absorption band in IR from 1660-1770 cm-1. Aldehydes show two characteristic C-H absorptions between 2700-2760 cm-1 and 2800-2860 cm-1. Saturated aldehydes absorb near 1730 cm-1 while aromatic aldehydes and α, β- unsaturated aldehydes absorb near 1705 cm-1. Saturated ketones and cyclohexanones absorb near 1715 cm-1 while aromatic ketones and α, β- unsaturated ketones absorb near 1685-1690 cm-1. Cyclopentanones absorb around 1750 cm-1.
In 1HNMR the aldehyde protons absorb near 10 δ with a coupling constant , J = 3Hz. Hydrogens on the carbon next to aldehyde group absorb near 2.0-2.3 δ. Methyl ketones show a sharp three proton singlet near 2.1 δ.
To purpose:
A structure for ketone or aldehyde with the following descriptions.
C7H14O, IR: 1710 cm-1; 1HNMR: 1.02 δ (Rel.area=4.50), 2.12 δ (Rel.area=1.50), 2.33δ (Rel.area=1.00).

AI cannot "see" the molecules properly, and it therefore gives the wrong answer while giving incorrect descriptions of the visual images we're looking at. All of these compounds would be produced (I think). In my book, I don't see any rules about yield in this case, like explaining that one product would be present in less yield for this reason or that reason. Please explain why some of these produce less yield than others.arrow_forward
