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
1 Only perfect potatoes are suitable for long-term storage. 2  Place the potatoes in a cardboard box, paper bag or mesh bag to ensure good ventilation. 3  Store in a cool, humid and dark place (45-50Â° is the ideal temperature range).
Before placing the potatoes in storage, remove loose soil and take them indoors to further dry and cure. Cure potatoes at a temperature of 45-60 F (7-16 C) and high relative humidity (85 to 95 percent) for two weeks. Final healing of minor cuts and bruises and thickening of the skin occurs during the curing process. For the next page in this section follow this link to Storing potatoes.
