Question:

Aluminium carbide on reaction with \( D_2O \) gives \( Al(OD)_3 \) and ‘X’. What is ‘X’?

Show Hint

When carbide reacts with water or heavy water (\( D_2O \)), it forms hydroxide (\( Al(OD)_3 \)) and hydrocarbon products like methane (\( CH_4 \)) or deuterated methane (\( CD_4 \)).

The Correct Option is D

Solution and Explanation

Step 1: Write the reaction
\[ Al_4C_3 + 12D_2O \rightarrow 4Al(OD)_3 + 3CD_4 \] Step 2: Identify the product
From the reaction, the product \( X \) formed is \( CD_4 \), which is the deuterated methane. Thus, the correct answer is \( CD_4 \).
