Product Description

Electron Gas Carbon Tetrafluoride Tetrafluoromethane CAS 7440-59-7

 

 

Description:

 

Tetrafluoromethane, also known as carbon tetrafluoride, is the simplest fluorocarbon(CF4) . It has

a very high bond strength due to the nature of the carbon-fluorine bond.

 

It can also be classified as a haloalkane or halomethane.Because of the multiple carbon–fluorine bonds, and the highest electronegativity of fluorine, the carbon in tetrafluoromethane has a significant positive partial charge which strengthens and shortens the four carbon–fluorine bonds by providing additional ionic character. Tetrafluoromethane is a potent greenhouse gas.
