Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. Identical.

Sol. Both Fischer projections represent CHFDT with the same configuration (priorities F $>$ T $>$ D $>$ H). Tracing 1 $\to$ 2 $\to$ 3 with the lowest priority on a vertical bond in each projection gives the same sense for both, so the two projections represent the same molecule : identical.
