Chapter 23, Problem 8STP

Interpretation Introduction

Interpretation: Which is not a structural isomer of given compound needs to be determined.

  

Concept introduction: Structural isomer are molecules with the same molecular formula but having different bonding patterns and different atomic organization.

Answer to Problem 8STP

B is the correct option.

Explanation of Solution

The given compound is as follows:

  

The name of the compound is 1,4-hexadiene. It contains 6 carbon atoms and has two double bonds at carbon 1 and carbon 4.

The given molecule in option B is ${\text{CH}}_{\text{3}}{\text{CH=CHCH}}_{\text{2}}{\text{CH=CH}}_{\text{2}}$ . It is identical to the given structure of 1, 4-hexadiene.

Thus, the compound in B is not a structural isomer of the given structure in question.

Conclusion

Options A, C and D are structural isomers of So, options A, C and D are incorrect.
