In your lab notebook, draw the "correct" (or best)
Lewis structure for the molecule CS2.Now, answer the following questions about this molecule.What is the total number of valence electrons represented in the
Lewis structure of this molecule (or molecular ions)?How many lone-pairs of electrons are on the Catom?How many (σ) sigma bonds does this molecule have?How many (π) pi bonds does this molecule have?Does this molecule have resonance structures?YesNo
1. There are ________ valence electrons in the Lewis structure
of CH3CH2OH?
2. There are ________ valence electrons in the Lewis structure
of CH3CH2OCl?
1. How many valence electrons must be accounted for in the Lewis structure of chloroethane (C2H5Cl)?
2. Consider the four resonating structures of the phosphate ion:
Calculate the average formal charge on a single oxygen atom, such as the one shown in blue, as it appears on all resonance structures, A to D.
Express your answer numerically as a decimal or fraction.
a) number of valence electrons, lewis structure, electron
geometry, molecular geometry, bond angles, polar or non polar :
ICl4^-
B) lewis structure, electron geometry, molecular geometry, polar
or non polar, sketch or molecule: IO3^1, SCN^-, BH3
