Question

How many compounds have delocalized electrons? w in @ Christo alinha

Answer 1

the flow of electrons from one atom to other/several adjacent atoms in a molecule is known as delocalization.

resonance structures are the Lewis structure which have the same placement of atoms but different in the arrangment of electrons. A hybrid of the contributing structure represents the real structure of the molecule and is known as resonance hybrid. the resonance contributors are represented with double headed arrow .

(a)

the structure of compound A as follows:

MC-ç =CH-ça=cw Here pi elections can move towards the spr hybridized carbon atom. So pi electrons can inwolue in delodizatio Thus, this compound contains delocalized Electrons , The Structure of compound B is as follows in - HC-- moze =CH2 Here the lone paix elechons on nitrogen atom cannot move towards the sps (which to represented by X in above Equation hybridized carbon atom. Thus the compound does not alors contains de localized Eletrons. The structure of compound ó bs as follows: Here the lone paix electrons on oxygen atom cannot move towards the sp3 ex hybridized carbon atom. Thus this compound does not contains de localized Electrons.

The structure Dis as follows Here the pi electione con move Towards the spy by bridized carbon atom. So the pi eletrons can involve in ele localization. Thus this compound contoh delocalized Eletrons The structure of compound Eis of follows x Here the lone pair of CH, NHL, Elections on nitrogen atom el cannot move towards the sp3 hybridized carbon atom. Thus the compound does not contain delocalized Electrons

compounds 1 and 4 contains delocalized electrons
