could someone please give the procedure for the haloalkane preparation from alcohol. do we actually use conc. sulphuric acid for the preparation of bromoalkanes and iodoalkanes as stated in ''Edexcel AS Chemistry students book'' page-221 unit 2 OR we use conc. phosphoric acid as using sulphuric acid would oxidise the halide ion to its halogen.
Also when do we heat the mixture and when do we cool it down during the preparation?

Dehydrate alcohol to form alkene and then react the alkene with a hydrogen halide to form halogeboalkane.
