Consequently, glucose in solution exists as an equilibrium mixture of three forms, two of them cyclic (- and -) and one open chain. 565574. These interconversions occur back and forth until a dynamic equilibrium mixture is achieved in a process called mutarotation. Ketones undergo most of the same reactions as aldehydes, but they tend to be slightly less reactive. Fahlberg would soon grow wealthy, while Remsen merely grew irritated, believing he deserved credit for substances produced in his laboratory. The aromatic group is exemplified by benzene (which used to be a commonly used solvent in the organic lab, but which was shown to be carcinogenic), and naphthalene, a compound with a distinctive mothball smell.
