The characteristics of a polar molecule
網頁Molecules are held together by shared electron pairs, or covalent bonds. Such bonds are directional, meaning that the atoms adopt specific positions relative to one another so as to maximize the bond strengths. As a result, … 網頁According to Molecular orbital theory which of the following statement is incorrect? (1) LUMO level for C2 C 2 molecule is σ2px σ 2 p x orbital. (2) In C2 C 2 molecules both the bonds π π are bonds. (3) C2 C 2 is paramagnetic but C22− C 2 2 - is diamagnetic. (4) In C22− C 2 2 - ion there is one σ σ and two π π bonds.
