What is Delocalization? Delocalization happens when electric charge is spread over more than one atom. For example, bonding electrons may be distributed among several atoms that are bonded together.

What do you understand by delocalisation?

to remove from the proper or usual locality. 2. to free or remove from the restrictions of locality; free of localism, provincialism, or the like. to delocalize a person's accent. Also esp Brit delocalise.

Why does delocalisation increase stability?

Charge delocalization is a stabilizing force because it spreads energy over a larger area rather than keeping it confined to a small area. Since electrons are charges, the presence of delocalized electrons brings extra stability to a system compared to a similar system where electrons are localized.
