1.which of the following is the most polar bond? explain
n-f c-f h-f o-f

2. in the trigonal bipyramidal geometry, which position - axial or equatorial - do nonbonding electrons prefer? why?

3.under what circumstances is the molecular geometry around a single central atom the same as the electron group geometry around the central atom?

4. if all of the electron groups around a single central atom are bonding, and the same outer atom is bonded to the central atom in each case, is the molecule polar, nonpolar, or does it depend on the identity of the outer atom? explain

  • chemistry -

    H-F because its electronegativity differs the most (1.9)
