Anomalous behavior of oxygen is due to its (1) Small size and low electronegativity (2) Large size and high electronegativity (3) Large size and low electronegativity (4) Small size and high electronegativity

1. Small size and low electronegativity
2. Large size and high electronegativity
3. Large size and low electronegativity
4. Small size and high electronegativity

Correct answer: Small size and high electronegativity

Solution

Oxygen's anomalous behavior is primarily due to its small atomic size, which leads to strong interactions with other atoms, and its high electronegativity, which allows it to attract electrons more effectively than other elements in its group.
