Molecular Geometry: Discover the Fascinating World of Atoms and Bonding

Click For Summary
SUMMARY

The discussion centers on molecular geometry, specifically regarding the shapes possible for a molecule with sp3d hybridization. The correct answer to the posed question is that the tetrahedral shape is not possible, as it corresponds to sp3 hybridization with four bonding pairs. The other shapes listed—linear, seesaw, T-shaped, and trigonal bipyramidal—are valid geometries for sp3d hybridization, which involves five electron pairs. Participants emphasize the importance of understanding hybridization and its implications for molecular shapes.

PREREQUISITES

for this I have no idea
---------------------
Which of the following shapes is not possible for a molecule in which the central atom has sp3d hybridization?
a. linear
b. seesaw
c. T-shaped
d. tetrahedral
e. trigonal bipyramidal
The hybridization somewhat refers to how many things the central atom is, or can be, bound to. sp3d is 1 + 3+ 1 = 5 things (electron pairs count as things).

Are you sure this question is correct? The only one that seems possible is trigonal bipyramidal since that connects to 5 things. Linear is, I think, just 1 thing (acetylene), seesaw sounds like a joke answer, T-shape also sounds like a joke answer, and tetrahedral means 4 things (methane). Ask your teacher if that question has a typo.
 
I just realized actually those funny names are sub geometries of the trigonal bipyramidal which all can have up to five legs, the only one that can't it seems is the tetrahedral which has 4 bonding pairs and 0 non-bonding pairs.
