WebA better leaving the group leads to faster reaction rates. A polar protic solvents, which can stabilize the ionic intermediates is favoured. Selectivity of E1 Reactions. E1 reactions mostly favour the more stable alkene as the major product. Favourable conditions for E1 reactions are: good leaving groups. stable carbocations. weak bases. WebA good nucleophile needs to easily attack an electrophile. Having a negative charge improves nucleophilicity because the greater electron density assists in attacking the electron-poor electrophile. The ease of attack is also assisted by the nucleophile being smaller so that steric hindrance is limited. bcw gmbh hamburg

WebA good leaving group is a weak base because weak bases can hold the charge. They're happy to leave with both electrons and in order for the leaving group to leave, it needs to be able to accept electrons. Strong bases, on the other hand, donate electrons which is why they can't be good leaving groups. WebPlace the following groups in order of increasing leaving group ability. Place the worst leaving group at the top of the list. ... All halide anions except F- are good leaving groups because of their conjugate acids (HCl, HBr, and HI) have low pKa.
