Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. (a) 1 (b) 3.

Sol. The carbon bearing Cl (C₄) is attached to four different groups (H, Cl, CH₃, CH=CHCH₃): one asymmetric (chirality) centre. Stereocentres include asymmetric centres plus the sp² carbons whose group interchange interconverts cis/trans isomers: the two double-bond carbons C₂ and C₃ are also stereocentres. Total stereocentres = 3.
