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).
Storage: Store potatoes in a cool dry place. They will keep at room temperature for up to two weeks and longer when stored in cool temperatures. If potatoes are purchased in a plastic bag, remove them from the bag and place in a basket or other such type of a container so that they will have proper air circulation.
