Complete the mechanism for the generation of the electrophile
used for Friedel-Crafts alkylation with the following alkyl halide.
Add curved arrows, bonds, nonbonding electron pairs, and charges
where indicated.
There is a double bond in the 3rd step, but it wont let me create
an arrow from the Iron to the Cl. Can someone explain what I am
doing wrong in the second step? Thanks!

Friedel-Crafts alkylation reaction: It is a type of electrophilic aromatic substitution reaction in which an alkyl group is substituted onto the aromatic ring using anhydrous ferric chloride.
Anhydrous ferric chloride is a Lewis acid catalyst, where the halide ion attaches to the catalyst, so that the alkyl group can attach onto the aromatic ring.
The general representation of Friedel-Crafts alkylation reaction is given below:
The attack of alkyl halide onto ferric chloride is shown below:
The mechanism for the generation of electrophile is given below:

The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2.
