摘要：Prediction of number of π-bonds, σ-bonds, single and triple bonds of aliphatic unsaturated open chain and cycloalkynes is a vitally important tool for students of chemistry at undergraduate and graduate level for solving different kinds of problems regarding different chemical reactions. In this manuscript, we try to present a simple and innovative method for easy calculation of number of π-bonds, σ-bonds, single and triple bonds with the help of completely 8 (eight) new formulae.
