Show Answer
Answer:
Correct Answer: 16. (a)
Solution:
- Small size and high charge on $\mathrm{B}^{3+}$ makes it highly polarising. Therefore, in most of its compounds, boron forms covalent bonds.
Hence, both statement I and statement II are correct and statement II is a correct explanation of statement I.
