WebThe exact properties of a specific kind of bond are determined in part by the nature of the other bonds in the molecule; for example, the energy and length of the C–H bond will vary depending on what other atoms are bonded to the carbon atom. Similarly, the C-H bond length can vary by as much as 4% between different molecules. WebThe bond length is 0.142 nm. The bonds between atoms of carbon in the layers of graphite may be strong, but the bonds that are formed by carbon atoms between layers are quite weak. These atoms are held together by Van Der Waal's forces. This kind of attraction is caused by shifts in the cloud of electrons surrounding carbon nuclei.
