Answer:
The incomplete and varying inversion of configuration takes place at the chirality center.
Explanation:
When optically active alcohols react with HBr an SN1 reaction occurs.
In SN1 reactions an intermediate carbocation is formed in which the nucleophile can attack it on either side of the molecule. Therefore, there is a partial inversion of the center of chilarity of the molecule.
Answer:
Minimizes heat transfer
Explanation:
To keep my lunch from getting cold at the beach, a material the minimizes heat transfer will be the most desirable.
- Such material should be modified to prevent had transfer by convection, conduction and radiation.
- This kind of material is desirable because heat generally flows from a place of high amount to that of low amount.
- Since the food will mostly have a temperature higher than the ambient one, it is expected that heat will flow away from the food to the environment.
- This will make the food cold.
- If such heat transfer is prevented, then, the food will remain hot.
The answer to this question is D! The ball and stick model! Hope this helps :)
