Is fluorobenzene more reactive than benzene?

The para position of fluorobenzene is more reactive than benzene, once you take into account the 6:1 advantage that benzene has (due to all positions being equally reactive, being compared to one position in fluorobenzene).

Is fluorobenzene more reactive than toluene?

The decreasing order of reactivity towards electrophilic substitution reaction is as follows: Toluene > Methoxybenzene > Fluorobenzene….

Why is Iodobenzene more reactive than chlorobenzene?

Reactions. Since the C–I bond is weaker than C–Br or C–Cl, iodobenzene is more reactive than bromobenzene or chlorobenzene. These reactions proceed via the oxidative addition of iodobenzene.

Which of the following is least reactive towards electrophilic addition?

Pridine is least reactive towards `SE becuuse pyridine is resonance stablised as shown. Because of withdrwasl of ˉe′s from the ring by N atom. The ring is deactivated thereby resembing the benzene ring in nitrobenzene. So it is leasrt reactive towrards SE reaction.

Why is fluorobenzene more reactive?

This negatively charged complex will be more stable in fluorobenzene as compared to chlorobenzene because of high -I effect of Fluorine. So due to stablisation of product intermediate reaction fluorobenzene is more reactive than chlorobenzene.

Which is the correct order of reactivity most reactive to least reactive toward electrophilic aromatic substitution?

Therefore, the correct order of reactivity towards electrophilic substitution is Phenol > benzene > chlorobenzene > benzoic acid.

Which is more reactive towards electrophilic substitution fluorobenzene or chlorobenzene?

Why does phenol undergo electrophilic substitution?

Electron deficient species is known as an electrophile. Thus, due to the electron-donating effect of the hydroxyl group in phenol, electron density increases at the ortho and para position of the aromatic ring. So, phenol undergoes electrophilic substitution more easily than benzene.
