Answer to Question 1

c

Answer to Question 2

b

Answer to Question 3

b

Answer to Question 4

c

Answer to Question 5

a

Answer to Question 6

No. Meso compounds are compounds that contain chirality centers but possess a plane of symmetry. Because the substituents on each chiral carbon are different in streptimidone, it is impossible for any stereoisomer to have a plane of symmetry.

Answer to Question 7



Answer to Question 8

s

Answer to Question 9

R

Answer to Question 10

b

Answer to Question 11

ANS: Cl > OH > CO2CH3 > CO2H

Did you know?

Ether was used widely for surgeries but became less popular because of its flammability and its tendency to cause vomiting. In England, it was quickly replaced by chloroform, but this agent caused many deaths and lost popularity.

Did you know?

There are more nerve cells in one human brain than there are stars in the Milky Way.

Did you know?

As the western states of America were settled, pioneers often had to drink rancid water from ponds and other sources. This often resulted in chronic diarrhea, causing many cases of dehydration and death that could have been avoided if clean water had been available.

Did you know?

A recent study has found that following a diet rich in berries may slow down the aging process of the brain. This diet apparently helps to keep dopamine levels much higher than are seen in normal individuals who do not eat berries as a regular part of their diet as they enter their later years.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
