Aliphatic compound hydrogen, other elements can be bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine. The least complex aliphatic compound is methane (CH). Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in Bunsen burners and as liquefied natural gas (LNG), and acetylene in welding. The most important aliphatic compounds are: Important examples of low-molecular aliphatic compounds can be found in the list below (sorted by the number of carbon-atoms): Aliphatic compound In organic chemistry, hydrocarbons (compounds composed of carbon and hydrogen) are divided into two classes: aromatic compounds and
Endohedral hydrogen fullerene Endohedral hydrogen fullerene Endohedral hydrogen fullerene (H@C) is an endohedral fullerene containing molecular hydrogen. This chemical compound has a potential application in molecular electronics and was synthesized in 2005 at Kyoto University by the group of Koichi Komatsu. Ordinarily the payload of endohedral fullerenes are inserted at the time of the synthesis of the fullerene itself or is introduced to the fullerene at very low yields at high temperatures and high pressure. This particular fullerene was synthesised in an unusual way in three steps starting from pristine C fullerene: cracking open the carbon framework, insert hydrogen gas and zipping up
