Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following carbide can be used to prepare methane by its action with water? (1) Aluminium carbide (2) Beryllium carbide (3) Calcium carbide (4) Silicon carbideA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
\[\underset{alu\min ium\text{ }carbide}{\mathop{A{{l}_{4}}{{C}_{3}}}}\,+6{{H}_{2}}O\xrightarrow[{}]{{}}\] \[2A{{l}_{2}}{{O}_{3}}+\underset{methane}{\mathop{3C{{H}_{4}}}}\,\] \[\underset{beryllium\text{ }carbide}{\mathop{B{{e}_{2}}C}}\,+2{{H}_{2}}O\xrightarrow{{}}2BeO+\underset{methane}{\mathop{C{{H}_{4}}}}\,\] \[\underset{calcium\text{ }carbide}{\mathop{Ca{{C}_{2}}}}\,+{{H}_{2}}O\xrightarrow{{}}Ca{{(OH)}_{2}}+\underset{acetylene}{\mathop{{{C}_{2}}{{H}_{2}}}}\,\] \[\underset{silicon\text{ }carbide}{\mathop{SiC}}\,+{{H}_{2}}O\xrightarrow{{}}no\,reaction\]You need to login to perform this action.
