polyhalogen compounds
we need 10 examples for the polyhalogen compounds....please help me....need it urgently...
Describe the importance of organic chemistry?
This is the common method for preparing haloalkanes in laboratory. Alcohols can be converted to haloalkanes by substitution of - OH group with a halogen atom. Different reagents can be used to get haloa
Illustrate alum?
