According to widely accepted "Fluid mosaic model" cell membranes are semi-fluid, where lipids and integral proteins can diffuse randomly. In recent years, this model has been modified in several repects. In this regard, which of the following statements is incorrect

The Elingham diagram (Fig.) represents the formation of oxides of several metals together with oxides of C(i.e., CO and CO_2 ). The diagram is not to scale yet it can help in making a lot of predictions. Which of following statements is incorrect?

The approximate shape of a molecule can often be predicted by using what is called the valence-shell electron-pair repulsion (VSEPR) model. Electrons in bonds and in lone pairs can be thought of a ''charge cloud'' that repel one another nad stay as far apart as possible, thus causing molecules to assume specific shapes. The repulsive interactions of electron pairs decrease in the order: Lone pair - Lone pair gt Lone pair - Bond pair gt Bond pair - Bond pair These repulsive effects result in deviations from idealised shapes and alteration in bond angles in molecules. Which of the following statements is incorrect?
