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).

A molecule of ammonia (NH₃) has only single bonds. The atomic number of N is 7. Its electronic configuration is ȷ2, Ǩȸ so it needs 3 more electrons to complete its octet.

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

It is the element which possess tetravalent property and thus form covalent compound.

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

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.

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.
