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).
1 Store the sweet potatoes in a root cellar or other place with a temperature of at least 55Â°F. 2  The ideal temperature range is 55Â° to 60Â°F. 3  The roots should last for about 6 months. 4  When removing the potatoes from storage, remember to be gentle; do not dig around or else you will bruise the potatoes. You can buy slips from garden centers, nurseries, or local farmers. 2  You can also grow your own slips to plant in the spring. 3  In November (this is when the best of the new harvest will be out), go to your supermarket and look for unblemished and uncracked medium sweet potatoes. 4  One potato should yield about 12 plants.
