[citation needed] Formaldehyde inhalation has also shown to cause oxidative stress and inflammation in animals. Formaldehyde is the simplest aldehyde made of hydrogen, carbon and oxygen with the formula CH2O. Formaldehyde is one of a large family of chemicals known as volatile organic compounds which evaporates and become gaseous at room temperature. Formaldehyde is a reactive molecule and first in the series of aliphatic aldehydes. Formaldehyde, being the simplest aldehyde has a very simple structure. Its molecule consists of a carbon atom from which two hydrogen atom is attached by a single bond and a oxygen atom which is bonded to the carbon atom by a double bond. The detailed chemical and structural formula for formaldehyde (methanal) are given in the following points.
