Chemistry - STEREO ISOMERISM Question with Solution | TestHub

(a) The two CH₃ groups lie on opposite faces of the cyclopentane ring (one solid wedge, one hashed wedge), so the compound is the trans isomer :

Ans. trans-1,3-Dimethylcyclopentane

(b) The two Cl atoms lie on the same face of the cyclohexane ring (both hashed wedges), so the compound is the cis isomer :

Ans. cis-1,2-Dichlorocyclohexane
