Which of the following carbides reacts with H 2 O to form propane?
Options
- AA l 4 C 3
- BC a C 2
- CSiC
- DM g 2 C 3
Correct answer
D. M g 2 C 3
Step-by-step solution
M g 2 C 3 + 4 H O H → C H 3 - C ≡ C H + 2 M g ( O H ) 2 A. A l 4 C 3 + 12 H O H → 3 C H 4 + 4 A l ( O H ) 3 B. C a C 2 + 2 H O H → C H ≡ C H + C a ( O H ) 2 C. S i C + H O H → No reaction.
