How is the angle of BF3 120 degrees?

[prakhargupta3301]

Since it shows back bonding, shouldn't it be a little more than that?

Thanks but I've already been there.
My query was that BF3 already has trigonal planar structure by hybridization. And the predicted bond angle is 120 deg.
But, we know that it shows BB too. So why doesn't it increases the bond angle?

Which bond angle? all three? Is that possible?

So why doesn't it increases the bond angle?

What number would it increase to?

Um. I don't know.
Perhaps that answered my question. An increase in all three is just impossible. Perhaps I was only playing around with the idea of BB with just one F but it's with all three. Is that what you mean?

Yes (I can't speak for mjc, but that's what I was thinking)

Okay thanks for helping me!
