Answer #1

At the time of fractional distillation, the compound with lesser boiling point will be distilled out of the reaction by using the fractional distillation process and the remaining higher boiling point compound doesn't reach the column of fractional distillation, due to this there will be the temperature drop just after the first fractional distillation.

The above criteria will only be going to observed if the difference in boiling point is as high as upto 25C

After making a change, a team should ask: What did we expect to happen? What did happen? Were there unintended consequences? What was the best thing about this change? The worst? What might we do next? Too often, people avoid reflecting on failure. Remember that teams often learn very important lessons from failed tests of change. Briefly describe the changes recently made with you directly, or you may choose a change/experience you have made in the past. Either or. It...
