Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Identical.

Sol. One stereocentre carrying CH=CH₂, D, F and Cl (priorities Cl $>$ F $>$ CH=CH₂ $>$ D). Reading 1 $\to$ 2 $\to$ 3 in each Fischer projection (lowest priority D on a vertical bond in the first, on a horizontal bond in the second, with the required inversion) gives the same configuration for both : identical.
