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).
If you keep potatoes in the fridge they should not be stored at temperatures below 7 Â°C (45 Â°F). If, that is, you intend to use them for roasting for frying. At lower temperatures the starch in the potato breaks down giving a burnt look and a bitter taste after roasting.ccording to Keeping Food Fresh by Janet Bailey: Some foods need temperatures warmer than your refrigerator but cooler than your pantry. Fresh potatoes and winter squash for example keep best at a temperature of around 50Â°F. to 55Â°F.
