What is the elution order of compounds in column chromatography?
In column chromatography, compounds elute in order of increasing polarity. This means that less polar compounds will elute first, followed by more polar compounds.
What is the order in which compounds elute in column chromatography, with a focus on which compound typically elutes first?
In column chromatography, compounds elute based on their affinity for the stationary phase. Typically, compounds with weaker interactions with the stationary phase elute first, followed by those with stronger interactions. The compound that typically elutes first is the one with the least affinity for the stationary phase.
Do alkenes elute before alkanes in gas chromatography?
Usually, but not always. Depends on the bond position and polarity of the column. Alkenes are less likely to elute first on polar columns.
How the polarity of a compound will affect on both normal phase and reverse phase mode chromatography?
In normal phase chromatography, polar compounds are retained more strongly due to interactions with the polar stationary phase, while nonpolar compounds elute first. In reverse phase chromatography, the opposite is true: polar compounds elute first because they have less interaction with the nonpolar stationary phase, while nonpolar compounds are retained more strongly.
How does column chromatography separate a mixture of methylene blue and methyl orange?
Methylene blue and methyl orange will have different binding affinities with the column material, and thus one will pass through the column more slowly than the other. This will result in one of the compounds being eluted from he column before the other. The one with the weakest binding to the column will be eluted first.

In column chromatography separation of p-nitroaniline and o-nitroaniline which will be aluted first and why?
o-nitroaniline will elute first in column chromatography because it has a lower affinity for the stationary phase due to its higher polarity compared to p-nitroaniline. This results in o-nitroaniline moving more quickly through the column and being eluted first.
Which compounds elute first in non polar gc column?
In a non-polar GC column, compounds with lower polarity elute first. Non-polar compounds are less attracted to the non-polar stationary phase of the column, so they move through the column faster than polar compounds.
What are the instrumental details of the gel permeation chromatography?
Gel filtration or gel permeation is a process by which molecules can be separated according to their size(molecular weight) and sometimes shape. small molecules get trapped and slowed down in the pores of the beads but large molecules simply flow down the column..therefore larger molecules come out first.
Separation of hemoglobin and riboflavin by gel chromatography?
The hemoglobin can pass through the gel first because it has a higher molecular weight, or larger molecule which could not pass through the pores of the beads in the gel, while the riboflavin would flow slower.
What type of chromatography would be used to separate two proteins?
Size exclusion chromatography would be ideal for separating two proteins based on their size. This technique separates proteins by allowing smaller proteins to enter the pores of the stationary phase while larger proteins elute first.
How the polarity of a compound will affect on both normal phase and reverse phase mode chromatography?
In normal phase chromatography, polar compounds are retained more strongly due to interactions with the polar stationary phase, while nonpolar compounds elute first. In reverse phase chromatography, the opposite is true: polar compounds elute first because they have less interaction with the nonpolar stationary phase, while nonpolar compounds are retained more strongly.
The relative vapor pressures of the mixture components are important in GC Gas Chromatography but not in LC Liquid Chromatography Why is that?
In Gas Chromatography, before you can correctly separate and identify the components, you need to vapourise the mixture first. How fast a substance vaporises is dependent on their vapour pressure. In Liquid Chromatography, there is no need to vapourise the mixture and hence vapour pressure is not important here.
