Carbon is a unique element that completes its octet by forming four hydrogen bonds.
- All four hydrogen bonds= Methane
- 2 covalent, hydrogen bonds= Ethene
- 3 covalent, 1 hydrogen= Ethyne
The energy resource is inexpensive, helps with garbage disposal, and reduces the need for landfills, protecting habitat Biomass.
