Re: CH2O hybridization Post by Anna O 2C » Mon 1:24 am The hybridization will be sp2 because the s orbital can only form 1 bond and the 2 p orbitals must be combined with the s orbital to allow for 3 bonds to be made by the central atom.Established since 1991, Hiwonder is part of the Formal Chemical Group of Companies (more popularly known as cH2o). Hiwonder also supplies Formalphen’s class ‘O’ phenolic insulation foam for the construction industry.C + H2 + O2 = CH2O - Chemical Equation Balancer.Formaldehyde is usually described as a gas, but it also exists dissolved in water or other solvents. Formaldehyde (CH2O) - Formaldehyde is a naturally occurring organic compound with the chemical formula HCOOH.
