What are X and Y respectively in the following reactions X ¯ + D 2 O → C 2 D 2 + P Y ¯ + D 2 O → CD 4 + Q
Options
- AAlCl 3 , CaCl 2
- BBe 2 C , Al 4 C 3
- CAl 4 C 3 , CaC 2
- DCaC 2 , Al 4 C 3
Correct answer
D. CaC 2 , Al 4 C 3
Step-by-step solution
C 2 D 2 is deuteroacetylene and CD 4 is deuteromethane. These compounds can be preapred by deuterolysis of respective acetylide and methanide. CaC 2 is an acetylide and Be 2 C   &   Al 4 C 3 are methanides. These compounds on reaction with D 2 O , give deuteroacetylene and deuteromethane respectively. CaC 2   +   2 D 2 O → C 2 D 2   +   Ca OD 2 Al 4 C 3     +   12 D 2 O → 3 CD 4   +   4   Al OD 3
