$Ca{{C}_{2}}$

$A{{l}_{4}}{{C}_{3}}$

$M{{g}_{2}}{{C}_{3}}$

none of these

Answer

Explanation

Solution

Aluminium carbide $(A{{l}_{4}}{{C}_{3}})$ gives methane on hydrolysis. This is also called aluminium methanide. $A{{l}_{4}}{{C}_{3}}+12{{H}_{2}}O\xrightarrow{{}}\underset{Methane}{\mathop{3C{{H}_{4}}\uparrow }}\,+4Al{{(OH)}_{3}}$
