Aromatic compounds Flashcards
describe benzene
cyclic, planar molecule with formula C6H6
draw the bonding in benzene
draw Kekule’s model of benzene
draw the delocalised model of benzene
what evidence is there for the delocalised model of benzene
all C-C bonds are the same length
has a much lower enthalpy change of hydrogenation than expected
what are arenes
aromatic compounds with a benzene ring
what’re some uses of benzene
pesticides, pharmaceuticals
when arenes react what do they undergo
electrophilic substitution
Draw a Freidel-Carfts acylation and name the type of catalyst used
halogen carrier
Draw a nitration reaction of benzene
in phenols the carbon with OH group attached is always carbon 1
why are phenols more reactive than benzene
phenol has a higher electron density in benzene ring
draw salicylic acid
phenols partially dissociate so they are
weak acids
no
