Chapter 8, Problem 8.111MP

Interpretation Introduction

(a)

Interpretation:

The resonance structure of ${\text{OCN}}^{-}$ needs to be drawn and the formal charges needs to be assigned.

Concept introduction:

Resonance structures are defined as a set of two or more Lewis structures that explain electronic bonding. Resonance structure can explain the delocalized electrons that cannot be signified by a single Lewis formula with an integer number of covalent bonds.

Interpretation Introduction

(b)

Interpretation:

The ${\text{OCN}}^{-}$ resonance hybrid that makes the greatest contribution and which represents least contribution needs to be determined.

Concept introduction:

Resonance structures are defined as a set of two or more Lewis Structures that explain electronic bonding. Resonance structure can explain the delocalized electrons that cannot be signified by a single Lewis formula with an integer number of covalent bonds.

Interpretation Introduction

(c)

Interpretation:

Whether ${\text{OCN}}^{-}$ is linear or bent needs to be determined.

Concept introduction:

Resonance structures are defined as a set of two or more Lewis Structures that explain electronic bonding. Resonance structure can explain the delocalized electrons that cannot be signified by a single Lewis formula with an integer number of covalent bonds.

Interpretation Introduction

(d)

Interpretation:

The hybrid orbitals used by the C atom and the number of pi bonds C formed needs to be determined.

Concept introduction:

Resonance structures are defined as a set of two or more Lewis Structures that explain electronic bonding. Resonance structure is capable of explaining the delocalized electrons that cannot be signified by a single Lewis formula with an integer number of covalent bonds.
