Question

Formation of acetylene from calcium acetylide can be represented as
$C{a}^{2+}C\equiv C^{2-}+2H_{2}O\to H-C\equiv C-H+2O{H}^{-}+C{a}^{2+}$

• A. The stronger acid (acetylene) is displaced from its salt by a relatively weaker acid (water)
• B. The weaker acid (acetylene) is displaced from its salt by a relatively stronger acid (water)
• C. The weak acid (acetylene) is displaced from its salt by anothr weaker acid (water).
• D. The weaker acid (acetylene) is displaced from its salt by neutral substance (water)

Answer 1

The correct option is B The weaker acid (acetylene) is displaced from its salt by a relatively stronger acid (water)

Acetylene is a weaker acid than water since the extent of dissociation is relatively low. So, the correct answer will be option (b).
