Electron dot structure of HCHO in chemistry
Answers
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. It is one of the most important industrial chemicals. Formaldehyde is usually described as a gas, but it also exists dissolved in water or other solvents. Formaldehyde is a naturally occurring substance used in a wide variety of applications.
Other names – formalin, methanal, formol
