(a)
Interpretation:
The major product of a Fridel-Crafts alkylation with the given alkyl chloride has to be stated.
Concept Introduction:
The Friedel-Crafts alkylation reaction is an example of electrophilic
In Friedel-Crafts alkylation, the major product is determined by stabilization of an electrophile (a carbocation). A tertiary carbocation is more stable as compare to the secondary and primary carbocation and thereby tertiary carbocation gives major product.
(b)
Interpretation:
The major product of a Fridel-Crafts alkylation with the given alkyl chloride has to be stated.
Concept Introduction:
The Friedel-Crafts alkylation reaction is an example of electrophilic aromatic substitution reaction. This reaction takes place between benzene (mostly) and an alkyl halide in the presence of Lewis acid catalyst. The mechanism of the reaction comprises three steps. The first step is generation of an electrophile (a carbocation). The second step is addition of electrophile on the benzene ring. The third step is deprotonation to yield an alkylated product.
(c)
Interpretation:
The major product of a Fridel-Crafts alkylation with the given alkyl chloride has to be stated.
