Examine the following order of elution of compounds containing certain functional groups from fastest to slowest, and indicate which mistake has been made.

hydrocarbons, olefins, ethers, amines, ketones, aldehydes, esters, alcohols, aromatics, and carboxylic acids
Aldehydes and esters are switched.
Amines and aromatics are switched.
Alcohols and aromatics are switched.
Ethers and esters are switched.
Aromatics and esters are switched

II The fastest, cheapest, and most commonly used method to monitor organic chemical reactions is? (Spell out the answer carefully, including the hyphen, no caps.)

III You have an alcohol and an amine of comparable size (both 10 carbons) that you want to separate and isolate both by silica gel chromatography, either tlc or a column. Which of the following pure solvents or solvent mixtures would have the best chance of working? Remember you need to compromise-too non-polar or too polar won't work.
Hexane
ethyl acetate with a trace of ethanol
cyclopentane with a trace of diethyl ether
ethyl alcohol
methanol alcohol with a little water

IIII To use tlc, it is necessary to be able to see where the spots are after eluting and drying the plate. Which of the following are possible ways to see where the compounds are on the plate.
Most compounds make complexes when exposed to iodine vapor, and the iodine is intensely colored.
Some compounds are naturally colored, so you just need to look.
Tlc plates are available with special stationary phases (i.e., the silica gel) that allow many spots to be seen under UV light.
The spots on some tlc plates can only be seen on a midsummer's eve under the light of a crescent moon. (JRRT)
Some compounds can be seen under UV light becasue they are inherently fluorescent and usually glow brightly.
