Methyllithium, electrostatic potential polar covalent bond

Methyllithium, electrostatic potential map of, 37, 143 polar covalent bond in. 37 Methylmagnesium chloride,... 

FIGURE 2.3 (a) Methanol, CHjOH, has a polar covalent C-O bond, and (b) methyllithium, CHjLi, has a polar covalent C-Li bond. The computergenerated representations, called electrostatic potential maps, use color to show calculated charge distributions, ranging from red (electron-rich S-) to blue (electron-poor 5-L).
