Molecular Shape of OF2
Step 1: Find the Central Atom
Central atom is:
Look your line bond structure on page 1.
Step 2:
Count number of atoms bonded to the central atom (B)
# of atoms bonded to central atom = B =
Count number of lone pairs on the central atom (E)
# of lone pairs on central atom = E =
Step 3: Choose the ABE classification
Circle the correct ABxEy notation.
Recall, we use (A) to represent the central atom, (B) to represent the number of atoms bonded to the central atom, and (E) to represent the number of lone pairs
AB1E3 AB1E2 AB1E
AB2E AB2E2 AB2
AB3E AB3 AB4
Step 4: Use the Molecular Shape Table from your notes to select the molecular shape and bond angles.
Molecular Shape=
Bond angles =
Step 5: Use the Molecular Shape table from your notes to draw the ball and stick representation
Step 6: Determine Polarity
Is the central atom surrounded by identical electron groups?
Circle one: yes no
If the answer was yes, then the molecule is nonpolar. If the answer is no, then the molecule is polar.
Is the molecule polar?
Circle one: yes no
