Chemical Bonding and Molecular Structure question

2023 · Q113

NEETChemistryChemical Bonding and Molecular StructureMCQ+4 / −1

Given below are two statements:

Statement I : Hydrated chlorides and bromides of Ca,Sr\mathrm{Ca}, \mathrm{Sr}Ca,Sr and Ba\mathrm{Ba}Ba on heating undergo hydrolysis.

Statement II : Hydrated chlorides and bromides of Be\mathrm{Be}Be and Mg\mathrm{Mg}Mg on heating undergo dehydration.

In the light of the above statements, choose the correct answer from the options given below :

  1. A
    Statement-I is correct but Statement-II is false.
  2. B
    Statement-I is incorrect but Statement-II is true.
  3. C
    Both Statement-I and Statement-II are true.
  4. D
    Both Statement-I and Statement-II are false.

Correct answer: D

Hydrated chlorides and Bromides of $$\mathrm{Ca}, \mathrm{Sr}$$ and $\mathrm{Ba}$ are Ionic so undergo dehydration after heating. Hydrated chlorides and Bromides of $\mathrm{Be}$ and $\mathrm{Mg}$ are covalent so undergo hydrolysis on Heating.
