**Practical aspects of radical halogenation**Radical halogenation of ethane is a major industrial process, with thousands of tons of chloro- and bromoethane produced annually. However, radical fluorination and iodination are not practical.Using thermodynamic analysis (similar to one we did in class), explain why radical iodination and fluorination are not practical.

These energies can be used to analyze the feasibility of different halogenation processes based on the stability of the bonds involved. Fluorination and iodination present unique challenges due to the specific BDE values for their bonds.

Which statement correctly describes the formation of the halogen radical, in radical halogenation? Options: Light excites electrons from the X2 lone pair into the anti-bonding orbital, thereby breaking the bond and forming radicals. Light excites electrons from the X2 sigma bond into the anti-bonding orbital, thereby breaking the bond and forming radicals. Heat excites electrons from the X2 lone pair into the anti-bonding orbital, thereby breaking the bond and forming radicals. Heat excites electrons from the X2 lone pair into the anti-bonding orbital, thereby breaking the bond and forming radicals.
