Question

can it be said that if there are more resonance structures for a compound, then it will have more stability? Or is it true for Hyperconjugative structures?

Answer 1

Organic chemistry, the behavior of electrons differs when the elements other than that of the carbon atoms and hydrogen actively take part in the formation of molecular bonds.

The electronic factors influencing the organic reactions includes the electromeric effect, the inductive effect, resonance effects, hyperconjugation, etc. All these factors relate to the organic molecules, in a diverse manner.  Most of the biological molecules consist of a combination of these six elements: carbon, nitrogen, hydrogen, oxygen, sulfur, phosphorus. Yet, they do not prevent the organic compounds from taking on the diverse properties of their chemical reactivity and physical characteristics.

The organic molecules also exhibit the property of resonance or mesomerism. In Organic chemistry, the factor called resonance or Mesomerism describes the delocalized electrons within the certain molecules where one single Lewis structure does not express the bonds. An ion or molecule with these delocalized electrons can be represented by contributing several structures which are known as resonance structures.
