| $Al$ | $-1.66$ | $+0.55$ |
| $Tl$ | $+1.26$ | $-0.34$ |
Based on these data, which of the following statements is correct ?
$SF _{4}, BF _{4}^{-}, CIF _{3}, AsF _{3}, PCl _{5}, BrF _{5}, XeF _{4}, SF _{6}$
Assertion $(A)$ : Experimental reaction of $CH _{3} Cl$ with aniline and anhydrous $AlCl _{3}$ does not give $o$ and $p-methylaniline$.
Reason $(R)$ : The - $NH _{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl _{3}$ and hence yields $m$-methyl aniline as the product.
In the light of the above statements, choose the most appropriate answer from the options given below.
