S Hz Ja Total # of Valence Electrons: 3-D Model Sketch: Bond Angles: Lewis Structure (show all resonance structures if applicable): Molecular Shape: Any polar bonds in the molecule? Yes/No Molecular Polarity: Polar/Non-Polar H:0 Soluble or H2O insoluble?

Answer 1

Total valence electrons

2C= 4 ×2 = 8

2H = 1×2 = 2

2I = 7×2 = 14

--------------------------

= 24.

3D model sketch is

Н С с — с 1200 I Ht

Bond angle : 120⁰.

Molecular shape: Trigonal planar.

I : lewi's diagam I

C-H and C-I bonds are polar.

Molecule is polar .

H₂O is polar hence C₂H₂I₂ is soluble in H₂O.
