... Alkyl ammonium ions, R3NH+ X-, have pKa values in the range of 10-11 (ammonium ion, H4N+ X-, has a pKa ~ 9.25) The ammonium ions of aryl amines and heterocyclic aromatic amines are considerably less basic than alkyl amines (pKa ~ 5 or less). The nitrogen lone pair is less basic if it is in an sp2 hy ...

... • The oxygen atom in alcohols, ethers and epoxides is sp3 hybridized. Alcohols and ethers have a bent shape like that in H2O. • The bond angle around the O atom in an alcohol or ether is similar to the tetrahedral bond angle of 109.5°. • Because the O atom is much more electronegative than carbon o ...
