Overall transformation : Ar-H to Ar-R
Named after Friedel and Crafts who discovered the reaction in 1877.
Reagent : normally the alkyl halide (e.g. R-Br or R-Cl) with aluminum trichloride, AlCl3, a Lewis acid catalyst.
The AlCl3 enhances the electrophilicity of the alkyl halide by complexing with the halide.
Electrophilic species : the carbocation (i.e. R +) formed by the "removal" of the halide by the Lewis acid catalyst
The reactive electrophile, the carbocation is prone to rearrangement to a more stable carbocation which will then undergo the alkylation reaction.

Friedel-Crafts reactions are limited to arenes as or more reactive than mono-halobenzenes
Other Lewis acids such as BF3, FeCl3 or ZnCl2 can also be used
Other sources of carbocations can also be used:
from loss of water from alcohols treated with acid such as H2SO4
from the protonation of alkenes by acid such as H2SO4
Alkylation products can also be obtained by the reduction of Friedel-Crafts acylation products

Um I don’t think your question is clearly stated but hope these notes can help:
Under the presidential public funding program, eligible presidential candidates receive federal government funds to pay for the qualified expenses of their political campaigns in both the primary and general elections. ... Fund the major party nominees' general election campaigns (and assist eligible minor party nominees).
Contributions are the most common source of campaign support. A contribution is anything of value given, loaned or advanced to influence a federal election.
Where do campaign contributions come from? - Most money comes from private givers, such as small contributors, wealthy individuals, political action committees (PACs), temporary fundraising groups, and candidates themselves.
If helped mark me the brainiest!!
True. The Atlantic ocean off of the east coast of the us has high salinity because evaporation significantly exceeds precipitation there.
<h3>What is evaporation?</h3>
- When a liquid changes from the liquid phase to the gas phase, it vaporizes in a way called evaporation on its surface.
- A high concentration of the evaporating component in the surrounding gas significantly slows down evaporation when humidity affects the rate of water evaporation.
- The process of a liquid turning into a gas is known as evaporation. On a hot day, it's simple to see when rain puddles "disappear" or wet clothing dries in the sun.
- Instead of dissipating under these circumstances, the liquid water evaporates into a gas known as water vapor. Evaporation happens on a global scale.
