Which of the following is a reason for the anomalous behavior of boron?
The high reactivity of boron with other elements in Group 13.
The low ionization energy of boron.
The small size and high electronegativity of the boron atom.
The ability of boron to form strong ionic bonds.
The small size and high electronegativity of the boron atom make it easy to form a variety of covalent bonds and oxidation states. This is the reason for the anomalous behavior of boron. Hence option C is the correct answer.
Option (A) is incorrect because boron is not particularly reactive with other elements in Group 13. Hence option A is incorrect.
Option (B) is incorrect because boron has a high ionization energy compared to other Group 13 elements. Hence option B is incorrect.
Option (D) is incorrect because boron does not typically form strong ionic bonds. Hence option D is incorrect.
