WebWhen a atom with lone pairs bonds, the bonds will move away from the lone pairs as much as possible. This is why water is a bent molecule, the two bonds are bending to be as far from the lone pairs as they can get. "Lone pair" is actually an older term. In modern usage the term "nonbonding electron pair" is preferred. WebA phosphoester bond is a bond between the phosphorous atom of a phosphate group and an oxygen atom.

WebJul 20, 2024 · In phosphate esters, diesters, and anhydrides the π bonding is delocalized primarily over the non-bridging bonds, while the bridging bonds have mainly single-bond character. In a phosphate diester, for example, the two non-bridging oxygens share a -1 charge, as illustrated by the two major resonance contributors below. WebATP is classified as an energy rich compound because: A) its complete oxidation to carbon dioxide releases a large amount of energy. B) it complexes with Mg2+. C) of the free energy released when the phosphoanhydride bond is cleaved. D) it has a relatively low free energy of hydrolysis. This problem has been solved!
