Which of the following reactions is not used in preparation or deuterium compounds using heavy water?
A.CaC₂ + 2D2O → C₂D2 + Ca(OD)₂
B.SO₃ + D2O → D2SO₄
C.2AlN + 3D2O → Al₂O₃ + 2ND3✓ Correct
D.Al₄C₃ + 12D2O → 3CD4 + 4Al (OD)₃
Explanation
Method of preparation of compounds using heavy water are as follows: 1. By calcium carbide- 2 2 2 2 2 2 ( ) CaC D O Ca OD C D → 2. By sulphur trioxide. 3 2 2 4 SO D O D SO → 3. By aluminium carbide. 4 3 2 4 3 12 3 4 ( ) Al C D O CD Al OD →
