Vedclass · Answer

(C) . $PCl_5$ undergoes hydrolysis to form $POCl_3$ and finally $H_3PO_4$ (phosphoric acid),which is a weak tribasic acid. Thus,statement $a$ is incorrect.$b$. In borazine $(B_3N_3H_6)$,the $B$ atom is electron-deficient and the $N$ atom has a lone pair. Nucleophiles attack the electron-deficient $B$ atom. Thus,statement $b$ is correct.$c$. $Al_2Cl_6$ is a non-polar,planar molecule (dimeric structure). Thus,statement $c$ is incorrect.$d$. $AlF_3$ is an ionic compound with a high lattice energy and does not exhibit covalent hybridization in the solid state. Thus,statement $d$ is incorrect.Therefore,statements $a, c,$ and $d$ are incorrect.

Select the incorrect statement:
$a$. $PCl_5$ forms a weak monobasic acid during hydrolysis.
$b$. In $B_3N_3H_6$,nucleophilic attack occurs on the $B$ atom.
$c$. $Al_2Cl_6$ is a polar and planar molecule.
$d$. In $AlF_3$,the hybridization of $Al$ is $sp^2$.
