Plastics are primarily derived from which type of compounds?

Explanation:
Plastics are long-chain polymers built from carbon-and-hydrogen compounds. Most plastics come from hydrocarbons found in fossil fuels, like petroleum and natural gas, which are processed into monomers such as ethylene, propylene, and styrene. Those monomers are then polymerized to form common plastics like polyethylene, polypropylene, and polystyrene. Water is not the source of the polymer building blocks, and metals or silicates are inorganic materials not used as the primary feedstocks for these polymers. This carbon-and-hydrogen basis is what makes plastics hydrocarbons.
