Question

question 11
the two molecules shown in the above figure are best described as ____________ isomers.

• enantiomers
• geometric (cis - trans)
• structural
• mirror image

Explanation:

Geometric (cis - trans) isomers have the same connectivity but differ in the spatial arrangement of groups around a double - bond. In the given molecules, the position of the methyl ($\text{CH}_3$) and hydrogen ($\text{H}$) groups relative to the double bond is different, which is characteristic of geometric isomers. Enantiomers are non - superimposable mirror images, structural isomers have different connectivity, and mirror image is a general term that is not as specific as geometric isomers in this context.

Answer:

B. Geometric (cis - trans)
