Abstract

In this approach, formulae-based mnemonics by using the classification of negative charge (localized or delocalized) have been highlighted by innovative and time economic way to enhance interest of students’ who belong to paranoia zone of chemistry for the prediction of hybridization state of carbon atom containing negative charge (one or more) and aromatic, anti-aromatic, non-aromatic behavior of different organic compounds. Here, I have tried to hub three (03) time economic mnemonics by including three (03) formulae for the prediction of hybridization state of carbon atom (containing negative charge), aromatic, anti-aromatic, and non-aromatic behavior of organic compounds. Educators can use these mnemonics in their teaching style in the classroom lectures after discussing conventional methods and its limitation to make chemistry intriguing. This article encourages students to solve multiple choice type questions (MCQs) on ‘Aromaticity of negative charge containing organic compounds’ at different competitive examinations in a time economic ground.
