Solution Summary

The solution is given by looking at the IR and HNMR spectra diagrams attached, and making the final conclusion on the identity of the molecule highlighted. Carboxyl and atom properties are used in conjunction with the diagrams to establish an idea over the identity of the molecule.

Solution Preview

The NMR looks very like a CH2=CH- group near an electronegative functional group, such as -COOH. The electronegative group raises the chemical shifts of nearby protons.

The H of -COOH is not apparent - probably because it has become -COOD by equilibrium with the deuterated ...
