WebA C–C bond has an approximate bond energy of 80 kcal/mol, while a C=C has a bond energy of about 145 kcal/mol. We can calculate a more general bond energy by finding the average of the bond energies of a specific bond in different molecules to get the average bond energy. Table 1: Average Bond Energies (kJ/mol) Single Bonds. Multiple Bonds. H ... WebCarbon suboxide, C 3 O 2, is a foul-smelling lacrimatory (tear-stimulating) gas produced by the dehydration of malonic acid, CH 2 (COOH) 2, with P 4 O 10 in a vacuum at 140 to … WebWhy does the middle C have an oxidation state of 0 in C3O2? The answer is best answered by considering its lewis dot structure. O=C=C=C=O is the lewis dot structure of carbon suboxide. The oxidation state in general can be explained as the number of electrons an atom can lose or gain in order to achieve stability. pool construction sri lanka
