I would like to you help me with my homework because I struggled with step 6. Can you help me with step 6, please?
![A₁ B₂ E₂=AB₂E₂
Molecular Shape of H₂S
Step 1: Find the Central Atom
Central atom is:__
(1) 5 Central atom A
Look your line bond structure on
page 1.
AB₂E
AB3E
H
H
Step 3: Choose the ABE classification
Circle the correct AB Ey 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

AB₂E2
AB2
AB3 AB4
Step 5: Use the Molecular Shape
table from your notes to draw the
ball and stick representation
(2) H Batom surrounding central atom)

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)
-2
# of lone pairs on central atom = E=
Step 4: Use the Molecular Shape Table from
your notes to select the molecular shape and
bond angles.
Molecular Shape- Bent
=~110°
Bond angles =
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

Expert Solution
![](/static/compass_v2/shared-icons/check-mark.png)
Step 1
The molecular geometry of H2S is bent. In molecular geometry only bond pairs are considered.
The electron pair causes repulsion, therefore, the shape of H2S appears like bent molecular geometry.
The electron geometry for H2S is tetrahedral. In electronic geometry bond pair and lone pair both are considered.
