Concept introduction:
By convention, the terms dextrorotation and levorotation (or laevorotation) represent the movement of plane polarized light clockwise or anticlockwise, respectively, for a compound as seen by the observer whom the light is approaching. The compound exhibiting dextrorotation is said to be dextrorotatory and that exhibiting levorotation is said to be levorotatory.
The dextrorotation and levorotation can be quantized by measuring the degree of specific rotation of the compound,
The value of dextrorotation is positive (+) and that of levorotation is negative (-).

The commonly prescribed formulation called Augmentin is a combination of the -lactamase inhibitor shown below with amoxicillin (shown above). It is used to treat childhood ear infections when resistance is suspected, and many kids know it as the white liquid that tastes like bananas. Which of the statements below are true statements? 1. The stereochemistry of the fusion between the four-and five-membered rings in the inhibitor and amoxicillin are different. 2. The inhibitor possesses enol ether and allylic alcohol functional groups while the antibiotic possesses a phenol and a secondary amide functional group. 3. Neither the inhibitor nor the antibiotic contains strained rings. 4. Both 1 and 2 are true.arrow_forward
