Correct statements regarding alkyl halides $\displaystyle (\mathrm{R}-\mathrm{X})$ among the following are : A. Alcohol being less polar solvent as compared to water, alcoholic KOH favours elimination reaction with $\displaystyle \mathrm{R}-\mathrm{X}$. B. Order of reactivity towards $\displaystyle \mathrm{S}_{\mathrm{N}}{ }^1$ mechanism is $\displaystyle \mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}_2-\mathrm{Cl}>\mathrm{C}_6 \mathrm{H}_5-\mathrm{CHCl}-\mathrm{C}_6 \mathrm{H}_5$. C. Non substituted aryl halides exhibit properties similar to alkyl halides. D. Vinyl chloride is an example of haloalkene and allyl chloride is an example of haloalkyne. E. $\displaystyle \mathrm{R}-\mathrm{Cl}$ can be prepared by reacting $\displaystyle \mathrm{R}-\mathrm{OH}$ with $\displaystyle \mathrm{SOCl}_2$ but $\displaystyle \mathrm{Ar}-\mathrm{Cl}$ cannot be prepared by reacting $\displaystyle \mathrm{Ar}-\mathrm{OH}$ with $\displaystyle \mathrm{SOCl}_2$. Choose the correct answer from the options given below :
