Shapes of molecules

The bond lengths and bond angles of various molecules can be determined experimentally. The values so obtained give us an idea about the shapes of molecules. The covalent molecules have definite shapes because the covalent bonds are formed along a particular direction. Thus, we can say that the covalent bond is directional in nature.
Note that this is in contrast to the ionic compounds in which the electrostatic forces of attraction are felt equally strongly in all the directions. Some examples of common covalent molecules and their shapes are given below in Table 5.4.
