What is the order of reactivity of the following compounds in electrophilic substitution?
Based on the above explanation we conclude that the increasing order of reactivity of the following compounds towards aromatic electrophilic substitution reaction is: D < A < C < B.
Which compound is the most reactive toward electrophilic aromatic substitution?
The compound which is most reactive towards the electrophilic substitution is the Methyl group. Activating groups attached to the benzene ring increase the reactivity of benzene towards electrophilic substitution.
Which compound shown is least reactive toward electrophilic aromatic substitution?
Benzenesulphonic acid is least reactive in an electrophilic aromatic substitution due to −M effect.
What is the correct order of decreasing reactivity fastest to slowest toward electrophilic aromatic substitution for the following compounds?
Therefore, the correct order of reactivity towards electrophilic substitution reaction is toluene > benzene > chlorobenzene > nitrobenzene.
What is the correct order of reactivity in electrophilic?
Therefore, the correct order of reactivity towards electrophilic substitution is Phenol > benzene > chlorobenzene > benzoic acid. Hence option B is the required answer.
What is correct order of Electrophillic substitution of following alkene?
So, the decreasing order of EA is: (II) – (alkene) > I – (alkyne) > III – (alkene with one EWG) > (IV) – (alkene with two EWGs).
Which is more reactive towards electrophilic reagent?
Therefore, o-hydroxy toluene is most reactive towards electrophilic reagent.
Which one is the least reactive towards electrophilic substitution?
Which is least reactive towards electrophilic?
So, Nitrobenzene molecule is less reactive towards electrophilic aromatic substitution.
Which of the following is least reactive towards electrophilic additions?
Which of the following is least reactive towards electrophillic…
- Answer. B.
- Among given is least reactive towards electrophilic addition * Because CNO2H=CH2 is electroedanating group equile is electrone group , So the electron density is less in this compound while.
Which is the correct order of reactivity most reactive to least reactive toward electrophilic aromatic?
Therefore, the correct order of reactivity towards electrophilic substitution is Phenol > benzene > chlorobenzene > benzoic acid.
Which of the following order is correct for decreasing reactivity towards ESR?
Correct Answer is: (C) I > III > II > IV Decreasing reactivity order for bromination (E.S.R.)
What are electrophilic aromatic substitution reactions?
Electrophilic Aromatic Substitution Reactions. Their lack of reactivity toward addition reactions is due to the great stability of the ring systems that result from complete π electron delocalization (resonance). Aromatic compounds react by electrophilic aromatic substitution reactions, in which the aromaticity of the ring system is preserved.
How do aromatic compounds react?
Aromatic compounds react by electrophilic aromatic substitution reactions, in which the aromaticity of the ring system is preserved. For example, benzene reacts with bromine to form bromobenzene.
What is the most effective site for aromatic substitution reactions?
Usually substitutents that activate electrophilic aromatic substitution like OH and CH3 are most effective at positions ortho and para to the substituent, so they direct the reaction to that site. You should be able to see that by drawing resonance structures.
What is the function of a catalyst in aromatic substitution reactions?
In general, the function of a catalyst (which is so often necessary to promote aromatic substitution) is to generate an electrophilic substituting agent from the given reagents. Thus it is necessary to consider carefully for each substitution reaction what the actual substituting agent may be.
