Question

Which of the following statement is True.

in presence of heat and light 1, 3-dichlorobutane is obtained with inversion of configuration.

For the reaction of CH₃OTs + X^– → CH₃X in the gas phase, the order of reactivity of halide ions is F^– > Cl^– > Br^– > I^–. But in methanol the order is reversed.

2-chloro-2-methyl propane is obtained as major product when 2-methyl propane reacts with Cl₂ in Sunlight.

The true statement is: "Direct halogenation of alkanes is not a good method of preparation of alkyl chlorides since this procedure gives a mixture of isomers."

This is because alkanes have multiple equivalent hydrogens. Chlorination is unselective; it can substitute at different carbon atoms. For example, propane chlorination yields both 1-chloropropane and 2-chloropropane. The reaction produces a complex mixture, making product separation difficult and the yield of any single isomer poor. Therefore, it is not a preferred synthetic route for pure alkyl chlorides.
