Which of the following is a Lewis acid?
(For polyatomic species, consider the Lewis acid behaviour of the central atom).
a. ) NH3
b. ) F-
c. ) H2O
d. ) PF5
e. ) BF3
Don't know why the options didn't show.
The others didn't show probably because you tried to copy and paste. That doesn't work. You must type what you want to post.
Draw the Lewis electron dot structure for each of the molecules you list. Then look to see which of the central ions can accept electrons.
Thanks for the headsup.
Yeh I have drawn the Lewis structures. How do I know which ions can accept electrons? Does that mean it has a unpaired electron?
