摘要：In this approach, formulae based mnemonics by counting lone pair of electrons (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 aromatic behavior and hybridization state of heterocyclic compounds. In order to ameliorate the field of chemical education, I have taken an enterprise to hub two economic mnemonics including two different formulae. This article encourages students to solve multiple choice type questions (MCQs) at different competitive examinations for a time being in an economic ground for the prediction of aromaticity and hybridization state of heterocyclic compounds containing two or more hetero-atoms. Educators can use these mnemonics in their teaching style in the classroom lectures after discussing conventional methods to make chemistry intriguing because the use of mnemonics in classroom lectures is an essential tool to become a distinguished educator.
