Fоllоwing аcid treаtment оf the intermediаte thiazolinone derivatives with acid, the resulting stable PTH derivatives are identified by C18 HPLC. Predict the relative C-18 (solid phase coated with hydrocarbon chains 18 carbons long) elution order (the order they come off the column) of the PTH derivatives of Ala, Ile, Arg, and Gln. Assume a mobile phase pH of 3 and briefly justify your predicted order. 1st 2nd 3rd 4th Justification:
