Which among the following is least covalent in nature?
- A \(\mathrm{NF}_3\)
- B \(\mathrm{BiF}_3\)
- C \(\mathrm{PF}_3\)
- D \(\mathrm{SbF}_3\)
Answer & Solution
Correct Answer
(B) \(\mathrm{BiF}_3\)
Step-by-step Solution
Detailed explanation
According to the Fajan's rule, smaller the cation, stronger is the covalent bond it forms, more is the covalent nature. \(\mathrm{Bi}\) forms largest cation in the group. So, it is least covalent in nature.
