Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Question Explanation: The question asks to identify the incorrect statement related to molecular structure, isomerism, and geometry.

Concept:

Functional isomerism, Conformational analysis, Center of symmetry (COS) and Molecular geometry.

Solution:

C₃H₆ (propene/cyclopropane) does not contain any chiral carbon → correct.

CH₃COOH (C₂H₄O₂ ) shows functional isomerism with esters (e.g., HCOOCH₃ ) → correct.

Cyclohexane shows conformational isomerism (chair, boat, twist forms) and it has a center of

symmetry; hence the statement that it does not have COS is incorrect.

Ethene has sp² -hybridised carbons and is a planar molecule → correct.

Final Answer: Option (C)
