Which of these is least likely to act as a Lewis base?
- A \(BF_3\)
- B \(PF_3\)
- C \(CO\)
- D \(F^-\)
Answer & Solution
Correct Answer
(A) \(BF_3\)
Step-by-step Solution
Detailed explanation
Electron rich species are called Lewis base. Among the given, \(B F_{3}\) is an electron deficient species, so have a capacity of electron accepting instead of donating. That's why it is least likely to act as a Lewis base. It is a Lewis acid.
