Read the given passage and answer questions follow : The replacement of hydrogen atom(s) in an aliphatic or aromatic hydrocarbon by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene),respectively. Haloalkanes contain halogen atom(s) attached to the sp^(3)hybridised carbon atom of an alkyl group whereas haloarenes contain halogen atom(s) attached to sp^(2) hybridised carbon atom(s) of an aryl group. Many halogen containing organic compounds occur in nature and some of these are clinically useful. These classes of compounds find wide applications in industry as well as in day-to-day life. They are used as solvents for relatively non-polar compounds and as starting materials for the synthesis of wide range of organic compounds. Chlorine containing antibiotic, chloramphenicol, produced by microorganisms is very effective for the treatment of typhoid fever. Our body produces iodine containing hormone, thyroxine, the deficiency of which causes a disease called goiter. Synthetic halogen compounds, viz. chloroquine is used for the treatment of malaria, halothane is used as an anaesthetic during surgery. Can we use halogen containing organic solvents to dissolve potassium chloride ?
