Homework Answers
If the -OH group on the bottom chiral C points to the right, then configuration is D
But if it points to the Left, then configuration is L
Thus option 1st is correct.
Since 2nd has no Chiral carbon atoms and is most stable molecule
3rd and 4th both projections are D . Since both -OH group points to the Right. Thus, both combinatios are wrong.
