Question
Can you help me with the H2S step-by-step for number (Step 6)? I need help with the central atom surrounded by an identical electron group. I need help with the molecule polar.
A₁ B₂E₂=AB₂E₂ Molecular Shape of H₂S Step 1: Find the Central Atom Central atom is: S AB₁E3 Look your line bond structure on page 1. AB₂E 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 AB3E (1) S Central atom A AB₁E₂ AB₁E AB₂E2 AB₂ AB3 Qlone AB4 (2) H B (atom surrounding central atom) E pair Step 5: Use the Molecular Shape table from your notes to draw the ball and stick representation H 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= 2 Step 4: Use the Molecular Shape Table from your notes to select the molecular shape and bond angles. Molecular Shape- Bent =~110° Bond angles = 2 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 19
