Science : Ch 04 – Carbon and its Compounds

Only 0.03% of atmospheric air contains carbon in the form of carbon dioxide. The natural concentration of  carbon monoxide  in  the air  is around 0.2 parts per million (ppm).

Buckminsterfullerene is an allotrope of carbon with ǩ0 carbon atoms, which are arranged in the shape of a football. Since this also looks like the geodesic dome designed by the US architect Buckminster Fuller

Carbon always forms covalent compounds by sharing its electrons with other at atoms.The two electrons shared by the atoms are attracted to the nucleus of both the atoms.

Reaction between an acid and an alcohol results in the formation of ester, and the reaction is named as esterification.

Carboxylic acids are compounds which contain a group also known as carboxyl group.

Denatured alcohol is the ethyl alcohol which has been made unfit for drinking purpose by adding small amount of poisonous substance like methanol, pyridine, etc.

Both Graphite and diamond being the allotropes of the same element , carbon, have similar chemical properties. So they undergo the same chemical reactions.

As the compound, CH₃CH₂CH=CH₂ contains four carbon atoms and a double bond attached to the first carbon, so the I.U.P.A.C name of CH₃CH₂CH=CH₂ is But-1-ene.
