Untitled flashcards and benzophenone in order of increasing polarity what determines the solubility of the compounds in the mobile phase in tlc. When benzophenone is mixed with water the results turned out to be insoluble because benzophenone is a pure hydrocarbon, which are very insoluble in water when benzophenone was mixed with methyl alcohol, it was soluble because methanol can hydrogen bond to the carbonyl oxygen of benzophenone.

Samples of benzophenone, malonic acid, and biphenyl were each tested with water, methyl alcohol, and hexane there were four test tubes for each sample: one tube was the control while the other three were filled with 1 ml of each solvent the trend for solubility follows “like dissolves like”. Example (2) – isobutyric acid has a solubility in water (at 25 0c) about one-third of its solubility in diethyl ether thus kd = 30 imagine 40 g of isobutyric acid dissolved in a mixture of 350 ml of diethyl ether and 1000 ml of water.
