All students preparing for NIT can download and read the PDF of these Organic Chemistry of Resonance Career Institute quota. As you will learn, if the bonds were of different types (one single and one double, for example), they would have different lengths. In general, molecules with multiple resonance structures will be more stable than one with fewer and some resonance structures contribute more to the stability of the molecule than others - formal charges aid in determining this. In the nitrite ion, the bond lengths of both nitrogen-oxygen bonds are equal. Study Tips 1. The resonance for HPO32-, and the formal charges (in red). The syllabus prescribed by the CBSE is the main material for the NEET (UG) Examination, which consists of three sections Physics, Chemistry, and Biology. e.g. (check the number of electrons by simply counting them).
