Note: a given bond type may be used more than once for these responses, or possibly not used at all.["covalent", "van der waals", "ionic", "hydrogen", "metallic"] bonding is similar to ionic bonding, except their are no high-electronegativity atoms present to accept any electrons that the present atoms are willing to donate.["van der waals", "metallic", "covalent", "hydrogen", "ionic"] bonds are the only primary bonds that are themselves directionally dependent. (hint: for one of the other primary bonds, a large collection of the particles will adopt a necessary geometry, but this is not directly caused by a constraint on where any two particles are allowed to "touch" one another.)["van der waals", "metallic", "covalent", "hydrogen", "ionic"] bonds are responsible for binding atoms together within a molecule of propane, whereas["van der waals", "metallic", "covalent", "hydrogen", "ionic"] bind separate propane moleculestogether in a condensed state.["ionic", "hydrogen", "metallic", "covalent", "van der waals"] bonds are responsible for binding noble gas atoms together in a condensed state. my guesses: metallic--> covalent--> van der waals--> hydrogen--> ionic only 2/5 were rightcovalent--> covalent--> van der waals--> covalent--> van der waals only 2/5 were right

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely.analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
