Detailed Solution

Statement I is incorrect because OF^- does exist. It is known as hypofluorite, and it is a stable ion. Hypofluorite ion has a similar structure to that of hypochlorite ion (ClO^-), except that it has a fluorine atom instead of a chlorine atom.

Statement II is correct. The HOF molecule does not ionize easily because the O-H bond in HOF is quite strong due to the high electronegativity of oxygen, which means that it requires a large amount of energy to break this bond and ionize the molecule. Additionally, the fluorine atom in HOF has a high electronegativity, which makes it difficult to remove an electron from the molecule. As a result, HOF molecule does not ionize easily.
