Which of the following behaves as a Lewis acid?
- A \(\mathrm{PH}_3\)
- B \(\mathrm{BF}_3\)
- C \(\mathrm{NMe}_3\)
- D \(\mathrm{CO}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{BF}_3\)
Step-by-step Solution
Detailed explanation
Electron deficient molecules are Lewis acids whereas electron rich compounds (having lone pair) are Lewis bases. \(\mathrm{NMe}_3, \mathrm{PH}_3\) and \(\mathrm{CO}\) are Lewis bases as they have electron pairs which they can donate. \(\mathrm{BF}_3\) is Lewis acid as it is…
