JEE Mains · Chemistry · STD 11 -p-Block elements - I
Given below are two statements: Statement \(I\): Group \(13\) trivalent halides get easily hydrolyzed by water due to their covalent nature. Statement \(II\): \(\mathrm{AlCl}_3\) upon hydrolysis in acidified aqueous solution forms octahedral \(\left[\mathrm{Al}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}\) ion. In the light of the above statements, choose the correct answer from the options given below :
- A Statement \(I\) is true but statement \(II\) is false
- B Statement \(I\) is false but statement \(II\) is true
- C Both statement \(I\) and statement \(II\) are false
- D Both statement \(I\) and statement \(II\) are true
Answer & Solution
Correct Answer
(D) Both statement \(I\) and statement \(II\) are true
Step-by-step Solution
Detailed explanation
In trivalent state most of the compounds being covalent are hydrolysed in water. Trichlorides on hydrolysis in water form tetrahedral \(\left[\mathrm{M}(\mathrm{OH})_4\right]^{-}\) species, the hybridisation state of element \(\mathrm{M}\) is \(\mathrm{sp}^3\). In case of…
