Which of these compounds would you expect to be least soluble in water? ch3oh nacl n2 nh3 not enough information?

             N₂ is least soluble in water.

Explanation:
                    Solubility of a solute in water mainly depends upon the creation of upcoming interactions between the solute molecules and water molecules. So, greater the interactions greater will be the solubility.
                    Sodium Chloride (NaCl) when added to water dissociated into Na⁺ and Cl⁻ ions. These positive ions interact with oxygen atom of water and Cl⁻ ions interact with Hydrogen atoms of water, Hence highly soluble in water.
                     Methanol (CH₃-OH) and Ammonia (NH₃) when added to water develops hydrogen bond interactions which are considered the strongest interactions among Intermolecular interactions.
                     Nitrogen Gas (N₂) is a non polar molecule, Hence, it fails to develop such interactions as that creater by the previous one, so, it is least soluble in water and bubbles out from water when tried to mixed.
