Question

Which of the following is not an ionizable compound?

• A. $Ca(OH{)}_2$
• B. $C{H}_4$
• C. $H_{3}P{O}_4$
• D. $N{H}_3$

Answer 1

The correct option is B $C{H}_4$

$Ca(OH{)}_2$ gets ionized into $C{a}^{2+}$ and $O{H}^{-}$ ions.
$H_{3}P{O}_4$ ionizes into $H^{+}$ and $P{O}_4^{-}$ ions.
$N{H}_3$ forms an $N{H}_4^{+}$ ions in solution.
But $C{H}_4$ is a covalent compound, hence it can't dissociate.
