Question:For a molecule who's central atom has a sp3d hybridization, which of the following shapes are possible? Linear, "Seesaw", or tetrahedral?
Answers:Both linear and seesaw shapes are possible with dsp3 (sp3d) hybridization. It depends on how many nonbonding pairs you have and how many groups are attached to the central atom.
The seesaw shape occurs when the molecule has the form AB4E, where A is the central atom, B represents the atoms attached to the central atom and E is a nonbonding pair of electrons attached to the central atom.
The linear shape occurs when the molecule has the form AB2E3, where A, B, and E are as defined as before.
Question:What hybridization of atomic orbitals of the central atom are necessary to accommodate the shapes of the molecules or polyatomic ions listed in the previous question. Enter your answers as a sequence of letters without commas or spaces; for example: ACBEE, using the key
D) sp3 d
E) sp3 d2
Answers:A) AsF5.... SP3D..D
C) BF3 ....SP2.......B
your answer is DABCE
Answers:both are sp2 H3CHC=CHCH3
Question:What is the maximum number of hybridized orbitals formed by an oxygen atom?
Answers:Oxygen cannot expand its octet (in the way that sulfur can) because it does not have an empty d orbital available to it.
Therefore the largest number of hybridized orbitals is going to be 4
Example: in water, the central O atom is sp3 hybridized.
14. Checking Hybridization Theory with XH_3 :Freshman Organic Chemistry (CHEM 125) This lecture brings experiment to bear on the previous theoretical discussion of bonding by focusing on hybridization of the central atom in three XH_3 molecules. Because independent electron pairs must not overlap, hybridization can be related to molecular structure by a simple equation. The "Umbrella Vibration" and the associated rehybridization of the central atom is used to illustrate how a competition between strong bonds and stable atoms works to create differences in molecular structure that discriminate between bonding models. Infrared and electron spin resonance experiments confirm our understanding of the determinants of molecular structure.
