Which of the following statements is true concerning the two compounds 2,3-dimethylpentane and 2,4-dimethylpentane?
A)Because the two compounds are structural isomers,they should have the same molecular formula.
B)Because the two compounds are structural isomers,they should have identical chemical properties.
C)Because the two compounds are structural isomers,they should have identical physical properties.
D)Because the two compounds are enantiomers,they should rotate polarized light in opposite directions.
E)Because the two compounds are geometric isomers,one should be cis and the other should be trans.

Quizplus · Accepted Answer

Structural isomers have the same molecular formula but different arrangement of atoms. Therefore, both compounds have the same molecular formula of C7H16 but have different structural arrangements. Option B, C, and E are incorrect because structural isomers do not have identical chemical or physical properties, and they are not always geometric isomers. Option D is also incorrect because enantiomers are mirror images of each other and rotate polarized light in equal and opposite directions.
