The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
Hi ,As you know from the structures of both the compounds that toluene has a methyl group on the benzene ring which is electron releasing group and hence activate the benzene ring by pushing the elctrons on the benzene ring. On the other hand nitro group on the benzene ring is electron withdrawing group which deactivates the benzene ring by withdrawing the electrons from the benzene ring . Now in the nitration attack of the nucleophile ( NO2 +) takes place. Hence reaction will takes place on that benzene faster which have more electron density on its ring which is the case of toluene.
This is a classic electrophilic addition reaction and can be carried out with any of the halogens except fluorine which just explodes and ruins the whole thing! What's actually happening is that bromine becomes polarised on approach to the hexene double bond due to the pi bond electrons. These 'attack' the positively charged side of the bromine molecule forming a bromonium ion and leaving a negatively charged bromide ion. This then attacks the reverse side of the molecule (because it is easier to access (hindrance) and because the carbon is positvely charged). This forms the final product which is a dibromohexane... Hope that helps Richard
The reason why fluorine has a higher ionization energy level than oxygen is because it is closer to the nucleus than is oxygen, therefore, it will take more energy to pull electrons from the nucleus.
It is always easier to cleanup something if you can get to it. * Streams (and their beds) can be worked on pretty easily. * Groundwater is pretty mysterious: flows are difficult to observe, drawdown to collect pollution depends on porosity, you don't know when the job is done
Either a glacier or Antarctica would be difficult to hike due to the frigid temperatures. Otherwise, very tall mountain ranges cause considerable challenges. But lower elevations, such as found in the Appalachian Mountains are easier to hike.
Health effects deriving from chemical exposures may not have immediate measurable effects and so can be difficult to identify. It is much easier to see that a broken arm follows a fall than to recognize that several years of exposure to benzene has resulted in a case of leukemia.

I feel it is easier
Easier
Ortho-para directing groups are those which can donate the electrons (lone pair or bonding pair by hyperconjugation) to benzene ring and create a negative charge on ortho and para positions by process of resonance so the attack of next incoming electrophile becomes easier as compare to unsubstituted benzene.
The opposite of "easier" is "harder."
no it is easier then closing your eyes
combustion as it is easier to tell that it has worked and more reliable.
In general humans are making survival more difficult for elephants. However, some humans are tyring to make it easier.
HTML is easier to maintain in most cases. If the code in not properly written, it is difficult.
functions -_-
This appears to be a transposition of the word easier(not as difficult).
