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 : Difference among hcl gas and hcl acid What is the basic difference among hcl gas and hcl acid? Briefly state the difference?
