Question

Define resonance.........​

Answer 1

Answer:

resonance is that property due to which a compound shows its variable resonating structures which includes delocalisation of charge( lone pairs, double bonds free radicals)

in order to gain stability

✴Resonance is defined as way of describing bonding in certain molecules or ions..

✴It is formed by combination of several contributing structures into a resonance hybrid in valence bond theory..

Uses of Resonance structures :

✴These are used when one Lewis structure for a single molecule can't be fully describe the bonding takes place between the neighbouring atoms relative to the empirical data for actual bond length between them...

✴Resonance is mainly performed to gain stability..

Examples of resonance :

In benzene :

✴It was proposed by kekule..

✴In benzene there are two resonating structures..

✴The structures are formed by the delocalisation of pie electrons in it..

✴The six electrons helps in the resonance which are pie electrons..

In ozone :

✴Ozone also have two major resonating structures..

✴That contribute equally to the overall structure of the molecule..

✴Both structures account for the needed of 18 electrons.

✴6 from the bonds and 12 from the lone pair present on oxygen atom.

✴They participate in resonance..
