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.

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

Cyclobutane is a cyclic hydrocarbon consisting of four carbon atoms where each carbon atom is attached to the two other carbon atoms and two hydrogen atoms.
