7th edition 3F.15 polarity and boiling points
Posted: Sat Nov 24, 2018 10:51 pm
The book asks to explain why AsF3 has significantly higher boiling point than AsF5 and in the solution its because AsF3 is a polar molecule. What makes AsF3 polar? Is it because the lone pair pushes the 3 F bonds down and so the vectors don't cancel out whereas in AsF5 all 5 bonds are spread out around As so the vectors there cancel out making AsF5 non polar?
