Chapter 23, Problem 23.86QP

(a)

Interpretation Introduction

Interpretation:

The given compound should be filled whether it is resonance structure, constitutional isomer, cis/trans isomer or same structure.

Concept introduction:

Isomer: Molecule has same molecular formula but different structural arrangement is called isomer.

Geometric isomerism (also known as E-Z isomerism or cis-trans isomerism): same molecular formula but different arrangement in the space. These isomers happen where you have restricted rotation in a molecule (double bond in the molecule). The functional groups are same side in the molecule is cis, the functional groups are opposite side is called trans isomer.

Constitutional isomer: (or structural) isomers differ in the connectivity they contain different functional groups and / or bonding patterns is called constitutional isomer.

Resonance: it is a process of delocalization electrons with in the molecule.

Chiral: Absence of a plane of symmetry or a center of symmetry is called chiral molecule, a non-superimposable on its mirror image is called chiral. A carbon atom is attached by the four different groups is called chiral carbon.

Enantiomers: Two stereoisomers that are mirror images of each other and they are non-supposable.

Diastereomers: Two stereoisomers that are non-mirror images of each other and they are non-supposable.

Answer to Problem 23.86QP

The given compound is diastereomers (a)

Explanation of Solution

To find: The given compound is resonance structure, constitutional isomer, cis/trans isomer or same structure

Answer to Problem 23.86QP

The given compound is resonance structure (c)

Explanation of Solution

To find: The given compound is resonance structure, constitutional isomer, cis/trans isomer or same structure

The given compound is resonance structure, constitutional isomer, cis/trans isomer or same structure needs to be known.

The given compound is resonance structure which is shown below.

Isomers have different sequence of bond types or connection in different order is called as resonance structure therefore the given molecule is resonance structure.
