Which of the following two combinations of reactants is more appropriate for the preparation of p-nitrophenyl phenyl ether? Fluo
VladimirAG [237]

Answer:

p-fluoronitrobenzene and sodium phenoxide is more appropriate

Explanation:

An ipso substitution is required to form p-nitrophenyl phenyl ether.

For this ipso substitution, an alkoxide anion needs to attack as a nucleophile at the carbon atom attached to fluorine atom and thereby substitute that F atom.

p-nitrophenoxide is an weak nucleophile as compared to phenoxide due to presence of electron withdrawing resonating effect of nitro group at para position.

p-fluoronitrobenzene is a good choice for nucleophilic attack by alkoxide anion as compared to fluorobenzene due to higher positive charge density at carbon atom directly attached to F atom. Higher positive charge density arises due to presence of electron withdrawing resonating effect og nitro group at para position.

So, p-fluoronitrobenzene and sodium phenoxide is more appropriate

The physical world around us behaves as it does partly because it’s made of a huge number of tiny molecules, each behaving rando
eduard
1. Weird things like the one described above do not happen on a ramdom basis becuause molecules usually move within any enclosure in a ramdom manner. Thus, it is not possible for some types of particles to aggregate in one point while other types of molecule aggreagate in another point. Based on the kinetic energy that is available for each particle, each particle will move random
through the available space, colliding with one another and with the wall of container.

2. It will be a difficult thing to live in a Maxwell' demon world because, things will happen unpredictably and one will never know what to expect next because anything can happen at anytime. For instance, if one is drinking a glass of water, some of the particles of the water may just decide to aggregate to one part of the cup and start boiling. So, for someone who is taking a glass of water, the water may start boiling right inside his mouth when he is drinking, that will be a bad experience. When one is driving a car, the petrol particles may just decide to freeze up when one is busy speeding on the highway; that can cause a very serious accident. Thus, a world where the Maxwell law operates will be a chaotic world.

Describe how you would obtain a beaker of pure water from salty water
Maslowich

Answer:

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.
