Hi,please
How many the enantiomers for 2,3,4 trihydroxy pentane ,according
van't Hoff rule?
also,I want to link the book or source on which the answer
thanks

Is this not a meso compound? And hence optically inactive!

look here   http://en.wikipedia.org/wiki/Meso_compound

There was no determining whether meso compound or optically inactive.

Start at the beginning - how many chiral centers do you have in the molecule? How many total diastereomers would you expect from that many chiral centers?

Now draw those out, and see if any would be identical to their mirror images (internal symmetry).

Not all of the stereoisomers are meso, some are chiral.
