Chapter 8, Problem 61P

Interpretation Introduction

Interpretation:

• The products of the given reaction have to be predicted.

Concept Introduction:

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.

Resonance hybrid: The actual structure with delocalized electrons is called a resonance hybrid.

Answer to Problem 61P

Correct Answer:

The compounds A, B, C, E, F, L, M, N, and O have delocalized electrons.

Explanation of Solution

Reason for correct options:

The above compounds all have delocalized electrons, which undergo electron movement.  The resonance structures can be drawn as shown above.

Hence, the correct options are A, B, C, E, F, L, M, N, and O.

Reason for in-correct options:

The remaining compounds do not contain delocalized electrons, conjugated system is absent.

Hence, the in-correct options are D, G, H, I, J, and K.

Conclusion

• The compounds containing delocalized electrons were predicted.
