Benzene.
WebScore: 4.8/5 (50 votes) . Benzene is a planar molecule having delocalized electrons above and below the plane of the ring. Hence, it is electron-rich. As a result, it is highly attractive to electron-deficient species i.e., electrophiles.Therefore, it undergoes electrophilic substitution reactions very easily. WebDec 26, 2024 · The reactive species in the nitration of benzene is (a) NO3 (b) HNO3 (c) NO2+ (d) NO2- hydrocarbons neet 1 Answer +1 vote answered Dec 26, 2024 by pinky …
WebApr 2, 2024 · The presence of reactive chlorine species in UV-Cl can be useful in removing contaminants that are resistant to hydroxyl radicals. Other matrix components such as Br– and HCO 3 – can scavenge with HO. and reactive chlorine species and form secondary radicals such as reactive bromine species and CO 3 –. WebTherefore, benzene becomes benzoate. Then, the other part of the ester (may be considered the ether portion) is put in front of the benzoate. Since the product is a methyl ester, the methyl comes before the benzoate. Methyl 3-nitrobenzoate mp 78 oC M.W . 181.15 Methyl benzoate bp 198-199 oC M .136 5 d 1.09 HNO3, H2SO4 CO2CH3 CO2CH3 NO2.

Webreactive. Making them meta directing group. Groups which produce —l effect in order of decreasing strength are: - NMe3, -N02, - Halogen Effect produces when substituent repel the electrons causing all the position in the ring to be more reactive than in substituted benzene. The effect make ortho and para positions more reactive than meta.
WebJan 23, 2024 · The reactivity of a benzene ring is governed by the electron density around the ring.
