Final answer:
Among the given options, H 2 (hydrogen gas) is likely immiscible with water. This is because water is polar and can interact well with other polar or ionic substances, whereas H 2 is nonpolar, and therefore cannot effectively dissolve in water.
Step-by-step explanation:
The question asks about the immiscibility or inability to mix with water. Among the given compounds, H 2 is likely to be immiscible with water. This is because water is a polar compound, meaning it has a separation of positive and negative charges, allowing it to mix or dissolve well with other polar or ionic substances. However, H 2 (hydrogen gas) is a nonpolar substance, its two hydrogen atoms share electrons equally and there is no charge separation. Thus, it cannot effectively mix or dissolve in water due to this lack of compatibility between polar and nonpolar substances.
