Q. Which of the following molecules acts as a Lewis acid?
A) (CH₃)₂O
B) (CH₃)₃P
C) (CH₃)₃N
D) (CH₃)₃B
Explanation
[Solution from source] In (CH₃)₃B boron has only six valence electrons and an empty p orbital, so it accepts an electron pair: a Lewis acid. The O, P and N compounds each carry a lone pair and act as Lewis bases. Answer (4).
