The specific rotation of (S)-carvone (at 20 degrees) is +61. A chemist prepared a mixture of (R)-carvone and its enantiomer, and this mixture had an observed rotation of -55. (a) What is the specific rotation of (R)-carvone at 20 degrees?
Aswer all parts of the question. A freshly prepared solution of αα ‑D‑glucose shows a specific rotation of +112°.+112°. Over time, the rotation of the solution gradually decreases and reaches an equilibrium value corresponding to [?]25 °CD=+52.5°.[α]D25 °C=+52.5°. In contrast, a freshly prepared solution of ?β‑D‑glucose has a specific rotation of +19°.+19°. The rotation of this solution increases over time to the same equilibrium value as that shown by the ?α anomer. A solution of one enantiomer of a given monosaccharide rotates plane‑polarized light to the left (counterclockwise) and is the levorotatory isomer, designated (−). The other enantiomer rotates plane‑polarized light to the same extent but to the right (clockwise) and is the dextrorotatory isomer, designated (+). An equimolar mixture of the (+) and (−) forms does not rotate plane‑polarized light. The optical rotation, the number of degrees by which plane‑polarized light rotates on passage through a given path length of a…
When a crystalline sample of α-glucopyranose is dissolved in water and the specific rotation is measured immediately, the observed rotation is +112°. When the same amount of βglucopyranose is dissolved, the observed rotation is +18.7°. However, over time, at room temperature, both solutions reach a specific rotation of +52.7°. Explain why these two solutions reach the same specific rotation over time.
