MCQ
$Be ( OH )_2$ react with $Sr ( OH )_2$ to yield an ionic salt. Choose the incorrect option related to this reaction from the following:
  • A
    Be is tetrahedrally coordinated in the ionic salt.
  • B
    The reaction is an example of acid - base neutralization reaction.
  • C
    Both $Sr$ and $Be$ elements are present in the ionic salt.
  • The elements $Be$ is present in the cationic part of the ionic salt.

Answer

Correct option: D.
The elements $Be$ is present in the cationic part of the ionic salt.
d
$Be ( OH )_2$ is amphoteric in nature.

$Sr ( OH )_2$ is basic in nature.

These two undergo acid - base reaction to form a salt.

$Be ( OH )_2+ Sr ( OH )_2 \rightarrow Sr \left[ Be ( OH )_4\right]$

(salt)
