Question

What is resonance and what are resonating structures ?

Answer 1

Hi friend,

■ In Chemistry , Resonance or mesomerism is a way of describing demoralized electrons within certain molecules or polyatomic ions where the bonding can't be expressed by one single Lewis structure.

■ When, more than one Lewis structure can be drawn, the molecules and ion is said to have resonance. The individual Lewis structure are turmed contributing resonance structure. Resonance is a common features of many molecules and ions in organic chemistry.

_______________________


$\huge\text{\underline{Resonance:}}$

It is the tendency of a system to oscillate at larger amplitude at some frequencies.


$\sf{\underline{Resonance\:structure:}}$

They are the canonical forms of a molecule with similar chemical formula but different arrangement of bonding.


$\sf{\underline{NOTE:}}$


⚫These frequencies are known as resonant frequencies.


⚫At these frequencies even a small driving force can produce large amplitudes.
