Question

Statement 1: $Al {(OH)}_{3}$ is amphoteric in nature.
Statement 2: $Al - O and O - H$ bonds can be broken with equal ease in $Al {(OH)}_{3}$

Moderate

A

Both statements 1 and 2 are correct
B

Statement 1 is correct and statement 2 is incorrect
C

Statement 1 is incorrect and statement 2 is correct
D

Both statements 1 and 2 are incorrect

Solution

$Al - O - H E . N : 1.5 3.5 2.1$
As E.N difference decreases , bond strength increases.
Hence bond strength of O-H > O-Al.
statement I is true but statement 2 is false.
