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).
We want to set up a solar cold storage for Potato preservation and seasonal vegetables preservation. Please advise me the cost of construction and cost of running expenses. Capacity would be 5000 MT to 10000 MT. Please revert at my mobile no 880 1822 680160.
