Ketones react with acetylide ion (Section 8.7) to give alcohols. For example, the reaction of sodium acetylide
Question:
Ketones react with acetylide ion (Section 8.7) to give alcohols. For example, the reaction of sodium acetylide with 2-hutanone yields 3-methyl-l-pentyn-3-ol:
(a) Is the product chiral? Is it optically active?
(b) How many stereo isomers of the product are formed, what are their stereo- chemical relationships, and what are their relativeamounts?
