Concept explainers
(a)
Interpretation:
The reason for the inconsistency of the IR spectrum with the originally proposed structure has to be explained.
Concept introduction:
IR spectral studies: It is a spectroscopic technique which is used to determine the
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
(b)
Interpretation:
The tautomer has to be drawn and the reason for it being more consistent with the observed IR spectrum has to be given.
Concept introduction:
IR spectral studies: It is a spectroscopic technique which is used to determine the functional groups present in the given compound sample by absorbing frequency in particular range with respect to the group present in the given sample.
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
(c)
Interpretation:
The source for the fairly intense signal at
