What will be the fermi temperature, if the number density is increased e a) Remains same b) Decreases by a factor of 4 c) Increa
1 answer:
Answer:
d) None of the options
Explanation:
Fermi temperature is directly proportional to number of density.
The relationship between Fermi temperature and number density given as follows
So When Fermi temperature increases then the number density will also increases.
So the option d is right because ,in the given option there is no any option which said that the number density will increase.

Answer:
D
Explanation:
- The rate of the Diels-Alder is orders of magnitude faster if there is an electron-withdrawing group on the dienophile. For example, replacing a hydrogen on ethene with the electron-withdrawing group CN results in about a 10^5 increase in the reaction rate.
- Other common electron withdrawing functional groups that will accelerate the Diels Alder reaction of dienophiles include aldehydes, ketones, and esters.
- In short, any functional group conjugated with the pi bond which can act as a pi acceptor will accelerate a Diels-Alder reaction with a typical diene.
