Harry creates a compound that contains only 1 pi (π) bond in total. The central atom has 4s2, 3d10, and 4p5. There are only 3 surrounding atoms with the electron configuration: 1s2 2s2 2p5. What is the formula and VSEPR shape for this compound? Explain how this is possible with respect to hybridized orbitals and how electrons are moved around to create this compound.
Two isomers share the molecular formula C3H4. In Structure A two ofthe carbon atoms are sp hybridized and one carbon atom is sp3 hybridized. In Structure B, two of the carbon atoms are sp2 hybridized and one carbon atom is sphybridized.
b)Draw “3D”-looking structures on paper, make a sketch of each of the isomers. (This should be a sketch of themolecules, not diagrams of overlapping orbitals!) Your drawing should show thecorrect molecular geometry around each carbon atom. [HINT: NEITHER of thesemolecules is planar!!! To draw them correctly, you will have to consider why!]
What statement about sigma(lowercase) bonds is true?
a)They are created by the overlap of p orbitals
b)They only occur in single bonds
c)It's the first covalent bond between two atoms in a molecular compound
d)They only occur between hybridized orbitals
e)none on the above
