Medium MCQ +4 / -1 PYQ · JEE Mains 2023

$\mathrm{Be}(\mathrm{OH})_{2}$ reacts with $\mathrm{Sr}(\mathrm{OH})_{2}$ to yield an ionic salt.

Choose the incorrect option related to this reaction from the following :

  1. A Be is tetrahedrally coordinated in the ionic salt.
  2. B The element $\mathrm{Be}$ is present in the cationic part of the ionic salt. Correct answer
  3. C Both $\mathrm{Sr}$ and $\mathrm{Be}$ elements are present in the ionic salt.
  4. D The reaction is an example of acid - base neutralization reaction.

Solution

$\mathrm{Be}(\mathrm{OH})_2$ is amphoteric in nature.<br/><br/> $\mathrm{Sr}(\mathrm{OH})_2$ is basic in nature.<br/><br/> These two undergo acid - base reaction to form a salt.<br/><br/> $$ \mathrm{Be}(\mathrm{OH})_2+\mathrm{Sr}(\mathrm{OH})_2 \rightarrow \underset{(\text{salt})}{\mathrm{Sr}\left[\mathrm{Be}(\mathrm{OH})_4\right]} $$
