How the lone pair of electrons of aromatic amines involved in hydrogen bonding despite their involvement in delocalization?
Wiki User
∙ 14y ago
When lone pair of nitrogen becomes involved in resonance process (deloclization) the aromatic ring acquires the negative charge so it is also a negative pole for partially positive hydrogen of other molecule and when lone pair is on nitrogen then hydrogen bonding is also possible, it may be said that it is deloclized hydrogen bonding among the molecules.

Write reasons cyclopentadiene is a usually acidic hydrocarbon?
Cyclopentadiene is a non aromatic compound but cyclopentadiene anion is aromatic in nature due to, 1- six pi electrons and 2- process of resonance so to stabilized itself as the aromatic anion the cyclopentadiene removes on hydrogen ion and behaves like an acid.
How many valence electrons will hydrogen have after chlorine steals electrons?
The hydrogen ion H+ is without electrons.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
How many electrons are there in the inner shell of hydrogen?
there are 2 electrons in the inner shell of a hydrogen atom.
What hydrogen atoms share electrons?
hydrogen atoms share electrons when it forms covalent bonds
What is benzene write its chemical equations?
Benzene is an aromatic organic molecule. Its formula is C6H6. The carbons are joined in a ring that is represented as a flat hexagon. The associated hydrogen atoms are represented as being attached to the individual carbon atoms but the electrons for sp2 bonding with the C-C bonding of the benzene molecule are actually distributed equally between each of the six carbon atoms - a phenomena referred to as electron delocalization or a superposition of so-called resonance structures. The delocalization contributes to benzene's thermodynamic stability and that of related aromatic compounds.

Why alkyl groups are o- and p- directing?
Because they donate the electrons to aromatic ring due to hyper conjugation (temporary bond breaking between carbon and hydrogen)
What is hydrogen embrittlement?
Hydrogen embrittlement is a phenomenon that occurs when some metals and alloys are exposed to hydrogen and absorb a sufficient amount of it. The presence of hydrogen interrupts the normal delocalization of bonding electrons in metal objects, and as a result, the metal object loses most or all of its ductility, breaking easily when deformed.Hydrogen embrittlement is the process by which various metals, most importantly high-strength steel, become brittle and fracture following exposure to hydrogen.
Why many aromatic hydrocarbons do not have any odor while compounds that have a pleasant odor do not have aromatic rings?
when aromatic compounds were first discovered they were called aromatic due to their plesant odours but as you have rightly pointed out compouns such as diatomic hydrogen have pleasant smells its is becuase of this that the meaning of aromaticity changed as aromatic compounds are saturated stable compounds its the notion of delocalised electrons that defines a aromatic compound now as this enhances the stabilty of the compound so chemically aromatic and aromatic are not particularly synoynymous any more in fact chemical aromacity has very little to do with aromacity and ewhat it does to the oliafactory centres that gives us the perception of smell
What are the characteristic of aromatic hydrocarbons?
Principal characteristics of aromatic hydrocarbons are:- the contain benzenic rings- frequently they have an agreeable odor- they burn with soot; this is a disadvantage- the ratio carbon/hydrogen is great
How many valence electrons will hydrogen have after chlorine steals electrons?
The hydrogen ion H+ is without electrons.
How many electrons do hydrogen gains or lost?
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.
Electrons that a hydrogen atom shares?
Hydrogen atoms share electrons in a covalent bond.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
How many electrons inn hydrogen?
Hydrogen is a metal element. There are 1 electrons in a single atom.
What are all the electrons of hydrogen?
There is only 1 electron in the hydrogen atom. More about electrons in wikipedia.
