Formaldehyde is a colorless, strong-smelling chemical used in building materials and many household products, and as a preservative in funeral homes and medical labs. Learn what we know about formaldehyde and cancer risk here. Formaldehyde (/ fərˈmældəhaɪd / (listen) fer-mal-duh-hahyd, also / fɔːrˈmældəhaɪd / (listen) for-) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). The Lewis Structure of formaldehyde (CH2O) shows how electrons are being shared among the carbon, oxygen, and hydrogen atoms to completely neutralize the overall formal charge. Moreover, the structure of CH2O is trigonal planar having the bond angles slightly distorted from the ideal percentage of 120°.

Structure of formaldehyde (methanal) The polar nature of its carbon-oxygen bond makes this a highly reactive compound. The oxygen atom attracts electrons more strongly than the carbon atom, resulting in a partial negative charge at one end of the compound and a partial positive charge at the other. Formation and structure. Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid- or base-catalysed.. Since formaldehyde exists predominantly in solution as a dynamic equilibrium of methylene glycol oligomers, the concentration of the reactive form of formaldehyde depends on temperature and Formaldehyde, being the simplest aldehyde has a very simple structure.

Formaldehyde structure

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 a chemical used widely by industry to manufacture building materials and numerous household products.
