Draw all steroisomers of pentane-1,2,3,4,5, pentaol using bold and hashed wedges. There should be two meso compunds and a pair of enantiomers.
This is kind of tricky for me because I have a reasonable answer from someone else here kind enough to help me but this is for an online homework, and the online program said that at least one was missing even though I drew four structures.
