Webbför 2 dagar sedan · Molecular Geometry of CH2O. The CH2O is a tetra atomic molecule where the bond angles for the hydrogen-carbon-hydrogen (H-C-H) and hydrogen-carbon-oxygen (H-C-O) are 116° and 122° and the structure is bent shaped. Moreover, the Valence Shell Electron Pair Repulsion (VSEPR) theory, says the molecular geometry of a molecule … Webb1) The electron pairs in the valence shell around the central atom of a molecule repel each other and tend to orient in space so as to minimize the repulsions and maximize the distance between them. 2) There are two types of valence shell electron pairs viz., i) Bond pairs and ii) Lone pairs. Bond pairs are shared by two atoms and are attracted ...
