Another question about gas chromatography, thanks for your help!
Homework Answers
The retention time is inversely proportional to boiling point and area of gas chromatograph is directly proportional to the amount of substance in gas chromatography.
Hence,
There is a lower percentage of compound 2 than 1 in the mixture.
Since retention time depends on lot of factors in gas chromatography

The original mixture contains petroleum ether, 1-hexene,
and 1-bromohexane in a 1:1:1 ratio.
Petroleum ether has the lowest boiling point range of
40-60ºC and the lower boiling point compounds travel through the
column faster than the higher boiling point compounds. 1-hexene
would have the second highest retention time with its boiling point
of 63ºC and 1-bromohexane would have the lowest with a boiling
point of 143ºC.
