Question

When heavy water reacts with calcium carbide, the product formed is:

• A. acetylene
• B. calcium hydroxide
• C. deuterium
• D. deutero acetylene

Answer 1

The correct option is D deutero acetylene

When heavy water reacts with calcium carbide, the products formed are deutero acetylene $\left(C_2{D}_2\right)$ and calcium deuteroxide $\left(Ca\right(OD{)}_2)$.

The reaction is as follows:

$Ca{C}_2+2D_{2}O\to C_2{D}_2+Ca(OD{)}_2$

Hence, option D is the correct answer.
