Carbon compounds containing more than one halogen atom are called polyhalogen compounds. Most of these compounds are valuable in industry and agriculture. Some important polyhalogen compounds are described as follows: Q : Dipole attractions-London dispersion Describe how dipole attractions, London dispersion forces and the hydrogen bonding identical?
