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.
i) Draw the FID spectrum for the original mixture (you will not
know the...
