The recrystallizaiton of benzoin and vanillin are two different procedures. explain what happens at the molecular level for each one.

next, explain the difference in the recrystallization procedures used depending on the compound to e purified and the nature of the contaminants.

what happens at the molecular level when benzoin and vanillin are recrystalized?

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
