Get started for freeThe reactions shown below are unlikely to occur as written. Tell what is wrong with each, and predict the actual product.
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.
Draw both cis- and trans-1,4-dimethylcyclohexane in their more stable chair conformations.
(a) How many stereoisomers are there of cis-1,4-dimethylcyclohexane, and how many of trans-1,4-dimethylcyclohexane?
(b) Are any of the structures chiral?
(c) What are the stereochemical relationships among the various stereoisomers of 1,4-dimethylcyclohexane?
Which, if any, of the following structures represent meso compounds? (Blue = N, green = Cl.)
What are the stereochemical configurations of the two diastereomers of(2S,4R)-2,4-octanediol? (A diol is a compound with two-OH groups.)
