TīmeklisEach lone pair is in an sp2 orbital, which is orthogonal to the pi system. The decrease in basicity relative to pyridine is due to the electron withdrawing heteroatom. The trend in basicity of the other three is due to the dipole moment of the molecule. The 1,4 positioning does not have a dipole moment, which decreases its basicity. number songs to ten https://olderogue.com
