What is the difference between localized and delocalized lone pairs?

If the lone pairs can participate in forming resonance contributors – they are delocalized, if the lone pairs cannot participate in resonance, they are localized.

What makes a lone pair localized?

A localized lone pair is a lone pair electron that does not participate in resonance.

Are lone pairs sp2 hybridization?

We know that the lone pair is held within a hybridized sp2 orbital because the double bond connected to the nitrogen has a pi bond (i.e. the unhybridized p orbital) which must contain a pair of electrons used to form the double bond.

Where are localized lone pairs?

Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure. Electron pairs are therefore considered lone pairs if two electrons are paired but are not used in chemical bonding.

Why are lone pairs considered to be delocalized?

A lone pair may seem to have some bonding characteristics; instead of sticking near one atom, it visits two atoms. A bond pair may appear to move between two different pairs of atoms. These electrons step outside the boundaries that Lewis’ theory has set for them, and we consider them to be delocalized.

How does a localized bond pair differ from a resonance hybrid?

A localized lone pair remains close to one atom. A localized bond pair travels between two atoms. Resonance hybrids necessarily contain some “abnormal” electrons. A lone pair may seem to have some bonding characteristics; instead of sticking near one atom, it visits two atoms. A bond pair may appear to move between two different pairs of atoms.

Why is the lone pair held within a hybridized sp2 orbital?

We know that the lone pair is held within a hybridized sp2 orbital because the double bond connected to the nitrogen has a pi bond (i.e. the unhybridized p orbital) which must contain a pair of electrons used to form the double bond.

Is the lone pair of nitrogen a hybridization?

And since we know that, that lone pair is de-localized, it’s going to occupy a P orbital, and so therefore this nitrogen is SP two hybridized, because we know SP two hybridization has three SP two hybrid orbitals, and one P orbital.
