Stronger bases

Which IS the stronger base in each of the following pairs Note This information will prove useful when you get to Chapter 9) 

Amide ion is a much stronger base than acetylide ion and converts acetylene to its conjugate base quantitatively 

Imidazole is a much stronger base than pyrrole Predict which 

Since bicarbonate is a stronger base than it is an acid (fcb2 > we expect that aqueous solutions of HCO3- will be basic. 

Tetrahydroisoqumoline is a stronger base than tetrahydroquinohne The unshared electron pair of tetrahydroquinohne is delocalized into the aromatic nng and this substance resembles am line m its basicity whereas tetrahydroisoqumoline resembles an alkylamine 

The compound shown is a somewhat stronger base than ammonia Which nitrogen do you think IS protonated when it is treated with an acid" Write a structural formula for the species that results 

Conjugate base of ethyl 3 oxobutanoate (stronger base) 

Alkylammes are slightly stronger bases than ammonia 

Ammonium ion is a weaker acid than pyridimum ion therefore ammonia is a stronger base than pyridine 

Cumulenic anions, C=C=C and C=C=C=C, without strongly electron-withdrawing substituents are much stronger bases than acetylides, "CsC- and are therefore also stronger nucleophiles. In view of the poor stability of the cumulenic anions at normal temperatures this is a fortunate circumstance the usual functionalization reactions such as alkylation, trimethylsilylation and carboxylation in most cases proceed at a sufficient rate at low temperatures, provided that the
