1.	1. Why alkyl halides are generally not prepared in the laboratory by free radical halogenation of alkanes?
Answer» The answer is simple because in free radical halogenation we get a mixture of mono-substituted, di-substituted, tri-sunstituted and even tetra-substituted halo-alkanes (alkyl HALIDES).EXPLANATION:Refer to the PIC (I am attaching) which shows the free radical halogenation of chlorine that gives a variety of products (as we REQUIRE only one type alkyl HALIDE not all in the form of mixture THUS we does not use this method)
