Question:

Imagine that another reaction similar to that in Problem 9.81 is carried out between sodium acetylide and (R)-2-phenylpropanal to yield 1-phenyl- 3-butyn-2-ol:

(a) Is the product chiral? Is it optically active?

(b) How many stereo isomers of 1-phenyl-3-hutyn-2-ol are formed, what are their stereo chemical relationships, and what are their relativeamounts?
