Original sentence: Although hybridisation schemes in transition metal chemistry can be used, they are not generally as accurate.Hybridisation theory is not as practical for quantitative calculations as Molecular Orbital Theory.It is an integral part of valence bond theory
Edited sentence: Although hybridisation schemes in transition metal chemistry can be used, they are not accurate and have little predictive power.Hybridisation theory is, however, considered less useful and less informative than Molecular Orbital Theory.It is an integral part of valence bond theory and the valence shell electron-pair repulsion (VSEPR) theory
