in base.
Complete the four boxes below with accurate Lewis structures, showing
all bonds and all lone pairs.
2. (2 points) Write a good Lewis structure for the compound HOF, showing
all bonds and all lone pairs.
Using the VSEPR approach, predict the geometry
of the electron distribution about O and the molecular (nuclear) structure
about O.
Electron distribution is tetrahedral.
Molecular structure is bent.
