(a)
Interpretation:
Number of carbon atoms introduced into compound 1 to make compound 2 has to be determined.
(b)
Interpretation:
Carbon atom in compound 1 that is involved in the reaction to make compound 2 has to be identified.
(c)
Interpretation:
Resonance hybrid of compound 1 has to be drawn.
Concept Introduction:
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Resonance Contributor: The appropriate structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds. Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
Resonance hybrid: The actual structure with delocalized electrons is called a resonance hybrid.
(d)
Interpretation:
Resonance hybrid that tells about the partial charge on the reactive carbon atom in compound 1 has to be explained.
