If the substituent X is an electron withdrawing group, the resonance structures are as shown in scheme 2. At some point two ortho carbons and the para carbon grow to be partially positively charged and X results in being partly negatively charged. Hence there will be a dipole minute in […]

Classification of Negative Charge Discriminate Hybridization with Aromatic and Anti-aromatic Behavior of Organic Compounds
Figure 1. Construction of cyclopropenyl anion (a), cyclopentadienyl anion (b) and cycloheptatrienyl anion (c) and phenyl carbanion (d) 2.2. Planarity of Organic Compounds Planarity is one of the very important attributes for prediction aromatic and anti-fragrant with non-aromatic actions of organic compounds. For aromatic and anti-aromatic behavior, the compound need […]
