A) \[Sc{{(OH)}_{3}}>Y{{(OH)}_{3}}>La{{(OH)}_{3}}\]
B) \[La{{(OH)}_{3}}>Y{{(OH)}_{3}}>Sc{{(OH)}_{3}}\]
C) \[La{{(OH)}_{3}}>Y{{(OH)}_{3}}>Sc{{(OH)}_{3}}\]
D) \[Y{{(OH)}_{3}}>La{{(OH)}_{3}}>Sc{{(OH)}_{3}}\]
Correct Answer: A
Solution :
[a] Size \[=S{{c}^{3+}}<{{Y}^{3+}}<L{{a}^{3+}}\] Ionic character \[=Sc{{(OH)}_{3}}>Y{{(OH)}_{3}}>La{{(OH)}_{3}}\] Basic strength \[=Sc{{(OH)}_{3}}>Y{{(OH)}_{3}}>La{{(OH)}_{3}}\]You need to login to perform this action.
