Question

The n which does not contribute to the basicity for the compound is

Answer 1

Hi there,

Your answer is N9

Those having basicity of Nine, the Electrons are sp2 hybridized where the lone combine within the aromatic pi system. However like those of Basicity of 1,3,7,8. They don’t have any lone pairs of Electrons that time removed from the rings. So once examine of those Compounds having 4,5,7,8,9 it found that those having 4,5,7,8 have alone combine of electrons however those having 9 donates its lone combine to the ring. Altogether different Nitrogen atoms, the lone pairs of electrons participate in resonance. It is possible that the lone pairs of electrons in N9 participate in Resonance by creating it unavailable by donation which makes it nonbasic.

Hope it helped.
