The structure formulas, the geometry around the carbon atoms and the polarity of two molecules having the molecular formula of C 2 H 4 O has to be determined. Concept introduction: Structural formula: The representation of each atom with their symbol in a bond-line structure of a compound is called as structural formula. The compounds having general formula C n H 2 n will have a double bond. Molecular geometry can be predicted from the structure by using the valence-shell Electron-pair repulsion (VSEPR) model. Count the number of valence electron pairs (bond pairs and lone pairs). Assume that the valence electron pairs form a structure that allows them to be as far away from each other as possible. If there are only two bond pair electrons, the molecule is linear. If there are three bond pair electrons, the molecule is shaped like a trigonal planar. If there are four bond pair electrons, the molecule is shaped as a regular tetrahedral. Repulsion between lone pair-bond pair of electrons effect the geometry of molecules. The polarity of a bond is arises due to the difference in electronegativity of atoms present in that bonding.

Why did the authors worry about the temperature-dependent solubility of the carriers in thebilayer? How did the authors determine whether the effect of freezing the lipid bilayer wasto decrease the solubility of the carriers (nonactin and valinomycin) or whether the effectwas to impair their ability to diffuse through the membrane (decrease their mobility)?
