Alkyl halides Flashcards
catalyst used during reaction of alcohol with HX
ZnCl2
alcohol with phosphorous trihalides
phosphorous acid and alkyl halide
alcohol with phosphorous pentahalides
alkyl halide POX3 and HX
impure method of preparation
free radical substitution/halogenation
what decides the reactivity of alkyl halides
bond energy
what decides reactivity when electrophile is attacking
bond polarity
alkyl halides mostly undergo
nucleophilic substitution reactions
carbo cation is formed in
Sn1 E1 addition to alkenes and alkynes
the most bad leaving group
alkoxide ion
favoured in polar solvents unimolecular two stepped reaction
Sn1
Sn1 mechanism reactants and products
tertiary alkyl halides 50% retention and inversion
B elimination reaction reactant
alcoholic KOH results in alkene
increase in temp and decrease in polarity favours
elimination reaction
more basic medium then
E2 is major mechanism
sodium in dry ether gives alkanes
wurtz synthesis
