Explanation:
In total reflux, the entire liquid exiting the condenser is returned back to the top of the distillation column. This means that there is no distillate product being collected and withdrawn from the system. All the liquid is being continuously recycled back into the column.
Given that total reflux is being maintained, the following can be determined:
a) Residue is nil: Since all the liquid is being refluxed back into the column, there is no liquid leaving the system as residue.
b) Distillate is nil: As mentioned above, in total reflux, no distillate is being collected. Therefore, the distillate is nil.
c) Reflux is nil: Reflux refers to the liquid that is returned to the column from the condenser. In total reflux, all the liquid leaving the condenser is refluxed back into the column. Hence, the reflux is not nil, but rather the opposite.
d) All of the mentioned: This option is incorrect because the correct answer is option 'B', as explained above.
In summary, during total reflux, there is no distillate being collected, which means that the distillate is nil.
