Formaldehyde (CH₂O) is a colorless, highly toxic, and flammable gas at room temperature. It is used in the production of fertilizer, paper, plywood, and some resins. It is also used as a food preservative and in household products, such as antiseptics, medicines, and cosmetics.

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 2D chemical structure image of formaldehyde is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of formaldehyde are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the

Formaldehyde is very soluble in water and organic solvents like ether, acetone, benzene, and alcohol. Sulphonated melamine formaldehyde condensates (SMF) are very similar in structure except that a melamine ring replaces the naphthalene double ring and the molecular weight is higher (Figure 4.7). They are only available as the sodium salt. A step-by-step explanation of how to draw the H2CO Lewis Structure (Formaldehyde). Formaldehyde (H2CO) is the simpiliest of a class of functional groups call Chain products are formed by further addition and condensation with the liberation of water and a mass molecule of phenol formaldehyde resin will form whose structure is shown in Fig. 30.
