Question

lab of speration of liquids by simple distillation and analysis by gas chromatogaphy liquids are ethyl acetate and butyl acetate

draw that models what happens when a 50:50 mixture of ethyl acetate and butyl acetate begins to boil.

which cpompound form that drawing move the slowest through this hypothetical coplumn does that compountd spend more time in the mobile phase or the stationary phase ?

what effect does column length have to speration efficency what might be a disadvantage of a very long column

would ethyl acetate or butyl acetate have the higher paritition coefficient why?

Explanation / Answer

when a 50:50 mixture of ethyl acetate and butyl acetate begins to boil, the component with high volatility vaporizes firest followed by the liquid with low volatility. Therefore, butyl acetate with more non-polar nature will have high volatility and ethyl acetate have low volatillity.

In a hypothetical column, polar compounds moves slowly while non-polar compounds moves fastly. Thus, ethyl acetate is more polar than butyl acetate it moves slowly and it spends more time in stationary phase.

Ethyl acetate would have high partition coefficent since it spends more time in stationary phase.

If column length is high, it takes more time to collect and uses more amount of chemicals
