Ans : The Lewis structure has a lone pair on the phosphorus atom , and the VSEPR formula is thus AX 3 E . Figure \(\PageIndex{4}\): (a) Molecules are always randomly distributed in the liquid state in the absence of an electric field. A whole molecule may also have a separation of charge, depending on its molecular structure and the polarity of each of its bonds. All of the dipoles have a upward component in the orientation shown, since carbon is more electronegative than hydrogen and less electronegative than chlorine: Other examples of molecules with polar bonds are shown in Figure \(\PageIndex{3}\). which words best describes the phenomenon which gives rise to a rainbow? (b) In H2O, the OH bond dipoles are also equal in magnitude, but they are oriented at 104.5 to each other.
