a. what role does temperature play in the solubility of a
compound in a given solvent? what is the ideal situation for
recrystallization regarding a chosen solvent and temperature?
b. when purifying a compound by recrystallization, you need to
consider the polarity of the solvent. how should the polarity of
your chosen solvent compare to the polarity of your product?
explain.

How is the bonding of intermolecular forces of an organic
compound like butanol similar to that of a suspension bridge,
whereas the intermolecular forces of butane is similar to putting
planks across a ditch? Remember to justify your answers.
Explain what characteristics of functional groups make an
organic compound lipophilic and what ones make a compound
hydrophilic. Explain why these characteristics are lipophilic or
hydrophilic.
Hydrogen bonding increases the intermolecular forces of
attraction and hence increased hydrogen bonding increases the
solubility in a liquid. For example, Methyl alcohol which is
organic in nature is miscible with water due to hydrogen bonding.
For the same reason acetic acid is soluble in water due to hydrogen
bonding. Acetic acid (CH3COOH) has got only one carbon atom and
steric hindrance of the methy group is low which permits water
(solvent) to get attached to solute. Can you elaborate...
