Observe the following statements 1. Heavy water is harmful for the growth of animals. 2. Heavy water reacts with Al ₄ C ₃ and forms deuterated acetylene. 3. BaCl ₂ 2 D ₂ O is an example of interstitial deuterate. The correct statements are
Options
- A1 and 3
- B1 and 2
- C1,2 and 3
- D2 and 3
Correct answer
A. 1 and 3
Step-by-step solution
(a) Heavy water is injurous to human beings, plants and animals since it slows down the rates of reactions occuring in them. (b) Heavy water reacts with aluminium carbide forming deuteromethane. array ll aluminium carbide Al ₄ C ₃ +12 D ₂ O & 4 Al ( OD )₃ & + deuteromethane CD ₄ array (c) In interstitial hydrates or deuterates, water molecules are present in interstitial sites or voids in the crystal lattice. e.g., BaCl ₂ 2 H ₂ O and similarly BaCl ₂ 2 D ₂ O are interstitial compounds.
