A bond formed when atoms transfer elentron is a bond

Chemistry

lubasha [3.4K]3 years ago
5 0
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.

A sample of gas (1.9 mol) is in a flask at 21 °c and 697 mm hg. the flask is opened and more gas is added to the flask. the new
garik1379 [7]

To solve this problem, we assume ideal gas so that we can use the formula:

PV = nRT

since the volume of the flask is constant and R is universal gas constant, so we can say:

n1 T1 / P1 = n2 T2 / P2

 

1.9 mol * (21 + 273 K) / 697 mm Hg = n2 * (26 + 273 K) / 841 mm Hg

<span>n2 = 2.25 moles</span>

choose a reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric aci
vagabundo [1.1K]

The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.

In the Friedel craft alkylation cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid. in the first step the cyclohexene produced carbocation in the presence of sulfuric acid by protonation. in the second step the `the carbocation undergoes nucleophilic by the benzene ring and produced cyclohexylbenzene. this is the mechanism  followed in the formation of the cyclohexylbenzene by the Friedel craft alkylation.

Thus, The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.
