Final answer:
Methanol (CH₃OH) is a nonelectrolyte because it does not dissociate into ions when dissolved in water; it remains as neutral methanol molecules in solution.
Step-by-step explanation:
The compound CH₃OH (methanol) when dissolved in water does not dissociate significantly into ions. Therefore, CH₃OH is considered as a nonelectrolyte. This is in contrast to strong electrolytes, which completely dissociate into ions in solution, such as HCl, or weak electrolytes which only partially dissociate, such as acetic acid, CH₃COOH. We know that alcohols are covalent compounds that tend to dissolve in water forming solutions with uncharged molecules, and do not produce a significant number of ions. Hence, methanol in aqueous solution largely remains as methanol molecules.
