Circle all true statements! a. A racemic mixture A) contains diastereomers. B) contains enantiomers C) is optically active. D) is optically inactive. b. The S_N1 reaction A) occurs through nucleophilic attack front the backside. B) is a bimolecular reaction. C) rate depends on the concentration of the nucleophile. D) rate does not depend on the concentration of the nucleophile. E) has the same first step as the E1 reaction. c. The E2 reaction A) results in the trans product. B) occurs out of a conformation, where the H that gets abstracted is anti to the leaving group. C) is a bimolecular reaction. Rank the following molecules. a. by boiling point (1 = lowest boiling point, 4 = highest boiling point)Explanation / Answer
10)
a)
racemic mixture is the one which has equal amount of R and S configuration
This is optically inactive
Answer: D
b)
SN1 is 1st order reaction where rate depends only the concentration of substrate and it doesn’t depend on the concentration of nucleophile. in Sn2 there is attack from back side
Answer: D
c)
E2 is bimolecular reaction
