revision of nitrogen Flashcards
what sign is used in the equation for keq
what is the equation for keq
at equilibrium what is generated
what pka does a strong acid have
what affects the steric hindrance of the lone pairs of nitrogen?
what affects the aqueous solubility of the compound containing nitrogen?
what reduces basicity of nitrogen containing compounds?
why is the nitrogen atom sp2 hybridised sometimes?
when can nitrogen act as an EDG
when can nitrogen act as an EWG
why is guanidine a strong base?
what does resonance do to stability?
do you know when tautomerism occurs?
why are free amine bases not water soluble?
why are salts water soluble?
what are common quaternary ammonium salts?
hydrobromide
hydrochloride
carboxylates (succinates,tartarates and citrates)
methanesulphonates
which functional group is responsible for biological activity? (loss of this group negates biological activity)
why cannot oxygen act basic?
due to oxygen having a higher electronegativity than nitrogen which reduces the ability of lone pairs of oxygen to be protonated
why is phenol a stronger acid than alcohols?
in which position of the aromatic rings do EWG stabilise the carboxylate anion?
what effect does EWG have on acidity?
what does EWG do to stability of carboxylate anions?
what does EDG do to stability of carboxylate anions?
what effect do EDG have on acidity?
