231293 Correct order of electrophilic substitution reaction is:

231294 Correct order of basic strength is

231295 Assertion: The carbocation $\mathrm{CF}_{3}-\stackrel{+}{\mathrm{C}} \mathrm{H}_{2}$ is less Stable than $\stackrel{+}{\mathrm{C}} \mathrm{F}_{3}$.
Reason: In case of $\mathrm{CF}_{3}-\stackrel{+}{\mathrm{C}} \mathrm{H}_{2}$, the strongly electron-withdrawing $-\mathrm{CF}_{3}$ group intensifies the +ve charge but in case of $\stackrel{+}{\mathrm{C}} \mathrm{F}_{3}$, the lone pairs of electrons on each of the three $F$-atoms overlap with the empty p-orbita of the carbocation carbon thereby dispersing the $+\mathrm{ve}$ charge.
