ochem lab final

strong nuc

lots of lone pairs

WB
all the LGs: I, Br, Cl

all the stuff with S: RS, HS, RSH, H2S

N≡C
SB
naked Os: HO MeO EtO

RC≡C

weak nuc

WB
concealed Os: H2O MeOH EtOH
SB
bulky bases: DBN DBU tBuO

sn1 reagant

weak nucleophile
agno3 in ETHANOL

sn2 reagant

strong nuc
NaI in acetone

e1 reagant

weak base
phosphoric acid

e2 reagant

strong base
NaOH, KOH

oxidation reagant

NaOCl (bleach) most safe
Jone’s reagant: CrO3/aq H2SO4, PCC

reduction reagant

NaBH4 most safe
LiAH4

extraction purpose

seperate acid (benzoic acid) and base (naoh) from neutral (biphenyl) and analyze via tlc
biphenyl willl have high rf, benzoic acid will have low rf, mixture will have 2 spots

sub rxn result

precipitation = product formed = preferred rxn
if after heat, slow rxn

e rxn result

GC: lowest bp = earliest peak

ox result

ir spectra
OH, CH, O=C/\
lower peak = more light absrobed = more intense vibration

theoretical yield

density x vol x 1/MW x MW product
