Question
Rank each of the following compounds in decreasing order of reactivity towards Friedel-Crafts alkylation.
Most reactive = 1; if a compound will not react, rank it as "non" rather than assigning a numerical value.
Compound A: iodobenzene _____1234non
Compound B: toluene _____1234non
Compound C: acetophenone _____1234non
Compound D: fluorobenzene _____1234non

Toluene 1 . - In toluene weakly activating methyl group is present. Activating group facilitate the fridele craft alkylaton (it is electrophilc substitution reaction).
Iodo benzene 2 - In iodo benzene iodine is weakly deactivating group. Iodine electronegativity is less than fluorine. deactivating capacity is less comparaded to fluorine.
Fluoro benzene 3 - In fluoro benzene fluorine is also weakly deactiving group. Frildel craft alkylation is slow.
Acetophenone 4 - In acetophenone moderatlely deactivating group carbonyl is present. Fridel craft alkylation is vey slow.
Ring activating groups facilitate fridel craft alkylation why because fridel craft alklyation is electrophilic substitution reaction.
