Although fluorenone is more polar than fluorenol, more specific interactions between fluorenol and silica account for its slow migration in thin-layer chromatography. below is a picture of the partial structure of silica. using abbreviated structures for fluorenol and fluorenone, show the specific intermolecular interactions between these compounds and silica. draw in extra silanol groups, as necessary. use abbreviations such as r2choh and r2c=o for the fluorene derivatives. a good drawing will show at least two molecules of fluorenol (interacting in different ways with silica) and one molecule of fluorenone and will take into account the review topics, above. be sure to include all non-bonding electrons in your drawing.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
