hmm, then why is CH3CH2O- a strong base then? it has a negative ion?
Also, how do u know if a reaction will go under an E1 or E2 reaction in a tertiary substrate? I know that in E2, only ANTI configuration of the leaving group and the hydrogen has to be present to work, and E1 configuration can take place in any circumstances , whether it be anti or syn....But , how would u know , for example, if a tertiary substarte is already in the anti configuration, if an E1 or E2 reaction will take place? FOr E2, does the nucleophile have to be basic, and for E1, only under neutral conditions will work? Like heating in pure ethanol??
also, in Sn1 reaction, i know that the best leaving groups are the one that are most stable, in other words, the one that fullfills the octet rule?? But isn't tertiary alchohols the best leaving group for Sn1 since they give the most stable carbocation intermediates? But my book says that a tertiary alcohol is one of the weakest leaving groups...
