Ketones react with sodium acetylide (the sodium salt of acetylene,) to give alcohols. For example, the reaction of sodium acetylide with 2-butanone yields 3-methyl-1-pentyn-3-ol
(a)Is the product chiral?
(b)Assuming that the reaction takes place with equal likelihood from both Reand Sifaces of the carbonyl group, is the product optically active? Explain.
