Q8 / 90 · JEE Main 2023 (13 Apr Shift 1) · Chemistry

$Be (OH)_{2}$ reacts with $Sr (OH)_{2}$ to yield an ionic salt. Choose the incorrect option related to this reaction from the following

A
Both $Sr$ and $Be$ elements are present in the ionic salt
B
$Be$ is tetrahedrally coordinated in the ionic salt
Correct answer
C
The element $Be$ is present in the cationic part of the ionic salt
D
The reaction is an example of acid-base neutralization reaction

Solution

$Be {(OH)}_{2}$ has amphoteric nature. $Sr {(OH)}_{2}$ has basic nature. These two compounds undergo acid-base reaction to get salt,

$Be {(OH)}_{2} + Sr {(OH)}_{2} ⟶ {Sr}^{+ 2} {[Be (OH)_{4}]}^{- 2}$

As $Be$ is present in anionic part.

Hence, the correct answer is option: 'C'.
