Question

please explain and show work thanks!

A certain compound was found to have a retention time of 14.3 minutes when analyzed by GC using tubular capillary GC column I. Under otherwise identical conditions how would the use of tubular capillary GC column II have affected the compounds GC retention time? Tubular capillary GC columns I and II are depicted below. The GC retention time would have been shorter than 14.3 minutes The GC retention time would have been longer than 14.3 minutes None of the above

Explanation / Answer

Polar compounds will generally have longer retention times on those GC columns which use
polar stationary phases. Hence the GC retention time would have been longer than 14.3 minutes.
