Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. (C) 4. The three ring carbons are stereogenic centres and the molecule has no symmetry (all substituents different). Each carbon can independently be 'up' or 'down', giving 2³ = 8 arrangements; reversing the whole ring (flipping the molecule over) pairs them into 4 distinct geometrical (cis-trans) isomers: all-cis, 1,2-cis-3-trans, 1,3-cis-2-trans and 1-trans-2,3-cis.
