Draw resonance structures for ortho, meta, and para attacks. Q16.5.2.
Also explained, Toluene, Aniline, and Nitrobenzene, and their interactions as substituents on a Benzene Ring. The following compound is less reactive towards electrophilic substitution than aniline?

Comparing this toluene, which is more reactive toward electrophilic substitution? Two good Lewis structures for benzene exist that differ only in their placement of double bonds. We never really need to know the number of resonance structures. Resonance Structures of NO2- Ion The resonance hybrid of NO 2 – suggests that each oxygen atom holds a partial charge of magnitude -½. Each Lewis structure that contributes to the resonance hybrid is a resonance structure. Structure, properties, spectra, suppliers and links for: Toluene, methylbenzene, 108-88-3, MeC6H5, CH3C6H5. Resonance Structures of Benzene as part of the Resonance Structures Video Tutorial Series! For example, I can draw six canonic resonance structures of the benzyl radical. Consider the intermediates of the following molecule during an electrophilic substitution. The resonance hybrid of this polyatomic ion, obtained from its different resonance structures, can be used to explain the equal bond lengths, as illustrated below.
Step by step drawing of each resonance structure of benzene. • Structure is planar, hexagonal 246 11.3: A Resonance Picture of Bonding in Benzene resonance hybrid 6 π-electron delocalized over 6 carbon atoms 11.4: The Stability of Benzene Aromaticity: cyclic conjugated organic compounds such as benzene, exhibit special stability due to resonance delocalization of π -electrons. Double check … Q16.5.3. The resonance structure is a hybrid of these theoretical resonance structures and is responsible for a gain in stability called the resonance stabilisation energy. I can only draw two canonic resonance structures for toluene — the same molecular structure only with an additional hydrogen on the side chain. This is a theoretical structure and there are two ways in which the double bonds can be arranged; the molecule can either be 1,3,5-cyclohexatriene or 2,4,6-cyclohexatriene. Explain. The whole concept is qualitative, so we can't draw any quantitative conclusions from it. Stability has much more aspects to it than just counting resonance structures. The classical example of resonance is benzene, C 6 H 6. But if you want to do it anyway, then of course 1 and 5 are the same, while 2 and 4 are not (they have positive charges on different atoms).
