In 2015 Destroyer, Organic #95 says that the most polar molecule will travel the furthest and elite last in column chromatography.

Organic #274 shows a TLC plate and the answer says that polar molecules travel the shortest distance.

I had always been under the impression that CC and TLC were very similar and the elution orders for the two were the same. Am I just reading or misunderstanding something in these questions or do that actually have different elution orders?

In Column Chromatography, the polar substance migrates slowest......as in elution rates, the concept is indeed similar. The polar substance traveled the shortest distance indeed, and would have the smallest Rf value.

Hope this helps
