31. The sulfamide functional group is an increasingly common structural feature used in medicinal chemistry. 32. A functional group is very similar to a chemical species and a chemical group. 33. Cyclobenzaprine, a skeletal muscle relaxant, also contains this functional group . 34. Dimethyl ether and ethanol would have dissimilar infrared spectra in the functional group region. 35. The chemical properties of fumaric acid can be anticipated from its component functional groups . 36. This colorless solid features the sulfonyl functional group and is considered relatively inert chemically. 37. The synthesis proceeds by utilizing the reactivity of the functional groups in the molecule. 38. Note that the epoxide and ester functional groups survive intact. 39. Many amino acids bear functional groups in the side chain. 40. Under this office the service is organized into four broad functional groups called divisions.
