Question

when dissolved in water, which of the following forms a molecular solution?
a) nano₃
b) ch₃oh
c) nacl
d) k₂so₄
e) naoh

Explanation:

Step1: Identify ionic and molecular substances

Ionic compounds dissociate into ions in water, while molecular compounds do not dissociate into ions. $NaNO_3$, $NaCl$, $K_2SO_4$, and $NaOH$ are ionic compounds. $CH_3OH$ is a molecular compound.

Step2: Determine molecular solution

A molecular solution is formed when a molecular - compound dissolves in water without significant dissociation into ions. Since $CH_3OH$ is a molecular compound and does not dissociate into ions in water to a large extent, it forms a molecular solution.

Answer:

B. $CH_3OH$
