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
Tracked: sorting tracks students creating inequality between students and their access.
Sorting creates high, middle, and low groups which each getting different educational experiences. The high will receive college ready skills whereas the low tend to be tracked for vocational work.
When using the canvas grade book for differentiated assignments; the cells of students who are not part of the assignment will be grayed out and not be accessible.
<h3>Canvas grade book: what is it?</h3>
- You can edit all of the grades for a particular grade book column using the grade book tool in Canvas.
- When you enter grades for an assignment that has been turned in (or when the cutoff for an online quiz has passed), Canvas can adjust any missing submissions (things that show as dashes) to a zero.
<h3>What do you mean by assignment?</h3>
- An assignment is a task that has been given to you by a higher authority.
- The word "assignment" is just the noun form of the verb "to assign," which is used to delegate tasks or jobs to others.
- The object you assign is referred to as an assignment.
