Question
1) What simple test can be performed to show that 3-chlorobenzoic acid is not eluted from the chromotography column? TLC possibly?
2) Predict the order of elution of a mixture of triphenylmethanol, biphenyl, benzoic acid, and methyl benzoate from an alumina column. I'm thinking most non-polar compounds elute first?
3) As soon as a chromotographic column is ready, why would it be important to allow the level of liquid in the column to drop to the level of the alumina before appying the solution of the compound to be separated?
