Two unique properties of atom are catenation and tetravalancey that leads to large number of carbon compounds around us. all the food item consists of carbon compoounds besides ethanol and ethanoic acid.
Ans. The ability of carbon atoms to form covalent bonds with other carbon atoms is the most unique of its bonding properties. This enables carbon to form long, continuous chains, branches and loops consisting of carbon and hydrogen in hydrocarbons and only carbon in carbon allotropes such as C60.This property is called catenation.This is the reason for the presence of the vast number of organic compounds in nature. e.g Diamond, coal, graphite.\xa0

Carbon has the unique property of forming bonds with carbon and forming large molecules of carbon. This property is called catenation.It froms strong and stable bonds.
It gives rise to an extremely large no. Of carbon compounds …
The outstanding property of carbon is to join infinite no. Of carbon , I.e their catenation property , this property is helpful for us , they form big
Catenation is unique property of carbon, because of catenation, carbon is able to form so many molecules by making bonds with other atoms & with itself as well. Because of this we are able to get so many useful molecules like acetic acid, ethenol etc.
