Vedclass · Answer

(A) $(I)$ $Li > Na$ (Reducing nature): Correct,as $Li$ has the highest negative standard electrode potential due to high hydration energy,making it the strongest reducing agent in aqueous solution.$(II)$ $BF_3 > BCl_3 > BBr_3 > BI_3$ (Rate of hydrolysis): Incorrect. The rate of hydrolysis increases with the size of the halogen atom and the decrease in back-bonding,so the order is $BI_3 > BBr_3 > BCl_3 > BF_3$.$(III)$ $B > C > N > O > F$ ($1^{st}$ ionization energy): Incorrect. The correct order is $B $(IV)$ $CCl_4 > SiCl_4$ (Boiling point): Incorrect. $SiCl_4$ has a higher boiling point than $CCl_4$ due to larger molecular size and stronger van der Waals forces.Therefore,only statement $(I)$ is correct. However,based on the provided options,there is no single option containing only $(I)$. Re-evaluating the question,if $(I)$ is the only correct statement,none of the options match. Given the standard nature of these questions,if we assume $(I)$ is the intended answer,none of the choices are correct. If we re-examine $(IV)$,$SiCl_4$ is definitely higher. If we re-examine $(I)$,it is correct. Since no option fits,we select the best possible fit or acknowledge the error.

Consider the following orders :-
$(I)$ $Li > Na$ (Reducing nature)
$(II)$ $BF_3 > BCl_3 > BBr_3 > BI_3$ (Rate of hydrolysis)
$(III)$ $B > C > N > O > F$ ($1^{st}$ ionization energy)
$(IV)$ $CCl_4 > SiCl_4$ (Boiling point)
The $CORRECT$ order$(s)$ are :-
