WebHomonuclear diatomic molecules feature relatively ‘pure’ covalent bonds since the electronegativities of the bonded atoms are the same (resulting in the bonded pair of electrons being almost equidistant from the two bonded nuclei). Examples of such covalent bonds can be seen in H2 molecules, Cl2 molecules, and O2 molecules. WebIn general, small uncharged molecules like O2 and CO2 can diffuse across freely, while charged molecules (Na+, H+) or polar molecules (glucose) cannot. Even water molecules diffuse only slowly across cell membranes, because water molecules are highly polar. Osmosis is the diffusion of solvent (water) molecules across a membrane. pink see through tank dress spaghetti strapWeb10 Jan 2024 · If molecules are non-polar, this means there are no dipoles or full charges on the atoms in the compound.
