The newly proposed formulae to calculate the number of π-bonds, σ-bonds, single and double bonds of aliphatic unsaturated open chain and cyclic olefinic hydrocarbons from the molecular formulae of organic molecules 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 the suggested bonds can be calculated from the molecular formulae as well as from any structural representation of a molecule corresponding to that molecular formulae. In this article we try to present a simple and innovative method for easy calculation of number of π-bonds, σ-bonds, single and double bonds with the help of 06 (six) new formulae.
