Show Answer

Answer:

Correct Answer: 16. (a)

Solution:

  1. Small size and high charge on $B^{3+}$ 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.
