2-Pentanone is the answer.
Explanation:
Answer:
a. 4
Explanation:
The number of theoretical plates is the number of discrete distillations that would have to be performed to obtain an equivalent separation of a discrete plate. This number is commonly used as a measure of separation efficiency and is a useful when comparing the performance of various chromatographic columns.
One theoretical plate is equivalent to one vaporization-condensation cycle, which is equivalent to one simple distillation. Thus a fractionation column that can attain the equivalent of three simple distillations would be said to have three theoretical plates.
