Why hydrogen bromide is electrophile?
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.
What are electrophiles and nucleophiles?
Electrophiles and Nucleophiles are atoms, bonds, or (small or small parts of) compounds that are involved in chemical reactions.Nucleophiles are "nucleus loving" which means that they want to give up electrons and gain a bond with another atom. These are usually negative or neutral compounds. (-OH base is a good example, the oxygen usually gives electrons)Electrophiles are the opposite, they are "electron loving" which means that they gain electrons (from the nucleophile to form a new bond). (A carbon-carbon double bond or hydrogen molecule can act as an electrophile for example.)
What happens with a Friedel craft acylation on o-xylene?
O-xylene is a benzene ring with two methyl groups in the ortho-positions. Methyl groups on a benzene ring act as o,p-directors, which means that they direct electrophiles to the carbon directly across or directly beside the existing methyl group. Friedel-crafts acylation creates the electrophile using a Lewis acid catalyst, however because there are two methyl groups side by side on o-xylene, the electrophilic addition is not as straightforward as described above. The two methyl groups direct the electrophile to different carbons, creating a mixture of products. As a result, there will be two products formed: One product will be a benzene ring with the electrophile and two methyl groups in a 1,2,3 orientation. The second product will be a benzene ring with the electrophile and two methyl groups in a 1,3,4 orientation (respectively). It is my understanding that the second product will be most predominantly formed, because it has the least steric hindrance (it is less crowded).
What part of the periodic table contains strong oxidizing agents?
Transition metal compounds, especially of first period (principally Mn with 7+ and Cr with 6+ charge).
Why only oxygen supports combustion and not hydrogen or nitrogen?
Hydrogen is not electronegative enough to act as a strong oxidizing agent, and the triple bond in the N2 molecule is difficult to break, making the gas largely inert. However, the halogens, particularly fluorine and chlorine can support redox reactions similar to combustion.
Why hydrogen bromide is electrophile?

What are TWO chemical properties of oxygen?
O is act as electrophile ie basic & more electronegative

What does Cesium act violently with?
Cesium reacts violently with water, oxygen and the halogens
Why the oxygen of a hydroxyl group act as a nucleophile or a base?
The hydroxyl group is the common denomination for a molecule consisting of an oxygen and a hydrogen atom connected by a covalent bond, in other words a O-H, where the oxygen atom has two or three (in case its an hydroxide anion) pair of free electrons, which can attack another atom with a deficiency of electrons and make a bond (acting like a nucleophile) or the same thing but attacking a proton H+ (atom with deficiency of electrons) acting in this case as a base. In both cases it acts as a nucleophile but when it attacks a proton or a molecule with a proton (like an acid) acts specifically as a base. I hope I could answer your question.
Why must an alkyl halide product be dried carefully with anhydrous calcium chloride before distillation?
My guess is, that any available water can act as a nucleophile and displace the halide producing the alcohol.
How is tamp act and sugar act similar?
because they were both on taxes
What word means to both the act of flying and the act of fleeing?
flight

How is the periodic law demonstrated with halogens?
Group 7 of the Periodic Table, known as the halogens, are all extremely reactive since they each contain seven valence electrons and only need one more to complete an outer shell. The periodic law suggests that recurring patterns of the properties of elements arise when they are arranged in order of increasing atomic number. This holds true as the halogens all act very similarly as each other in chemical reactions.
How are the stamp act similar to the sugar act?
I think because they are both taxes.
What is similar between the sugar act and the stamp act?
They both depend on taxes.
