SpletThe strength of the attractive force in a hydrocarbon chain increase as the size of the molecule increases. That is why short-chain alkanes (C 1 to C 4) are colorless gases, mid-length alkanes (C 5 to C 17) are liquids, while long-chain alkanes molecules (> C … SpletThe mechanisms by which abiotic, long-chain hydrocarbons are produced in natural alkaline hydrothermal systems are unknown, as only short-chain hydrocarbons (<5 carbons) have been experimentally observed to date. Here, we demonstrate how the hydrothermal reduction of bicarbonate into long-chain hydrocarbons (≤24 carbons) occurs through the …
