Answer – Isomer – The compound which has same molecular formula but different in the structural formula are called as isomers of each other’s.

According to the connectivity of the atoms in the structures there are different type isomers. If the compound has same connectivity, then it is called stereoisomers and if not then it is called as constitutional isomers.

Stereoisomers are the isomers in which the different in the spatial orientation of their atoms, means the different in the three-dimensional orientations of their atoms in space. The group of atoms are bonded together in fundamentally different ways then called as constitutional isomers.

For the stereoisomers there are again two type and it is configurational and conformational isomers. Configurational isomers have again two types that is geometrical and optical. The geometrical isomers have two types cis and trans and for the optical there are diastereomers and enantiomers.

The resonance structures different from isomers, because we know isomers has the same molecular formula but different structure and resonance structures are the delocalization of pi electron in the planar structures, so there are not changing the atoms and bonding, but there is change just the pi electrons in the system, so they are not isomers.

Resonance structures are Lewis structures drawn for a molecule when more than one Lewis structure is needed to explain the molecular structure. Resonance results in extended __________? of some electrons among more than two nuclei of the molecule. This results in lowering of kinetic and potential energies that imparts added stability to the molecule. Note. In covalent bond formation the bonding electrons are delocalized between only two atoms. Resonance is taking the delocalization of electrons between nuclei to the next...
