Answer: You interconvert any two groups on the chiral carbons. Explanation: For example, the structure of 2-brombutane is. We can convert this to its enantiomer by interchanging any two groups. We often interchange the groups on the wedges and dashes, as below. It is not immediately obvious that these are mirror images of each other. If we rotate the top structure 180 Â° about the axis and put it below our original structure, we get
In general, the optimum, long-term storage temperature for processing potatoes is approximately 45Â° F. For fresh market potatoes, a temperature of 40Â° F. is recommended. Seed potatoes may be stored at slightly lower temperatures (38Â° to 40Â° F.) for better weight loss and sprout control.
(However, they wonât keep as long as they would if kept at ~55Â°F.) In general, potatoes will keep for 1-3 weeks in the refrigerator, but this depends on when they were harvested before they got to you. Sweet potatoes should be stored the same way as white potatoes. The usual advice is not to refrigerate them, but they will tolerate refrigeration as long as they have been âcuredâ at 85Â°F for 5-8 days to allow the skins to dry out and harden. Raw whole potatoes can be stored wrapped or unwrapped.
