lewis structure shape

Postby Roni Touboul » Thu Nov 15, 2018 11:07 am

How many shapes are there for the lewis structures? (tetrahederal for example)

I think there are 11 we need to know:
linear, trigonal planar, angular, tetrahedral, trigonal pyramidal, trigonal bipyramidal, see-saw, t-shaped, octahedral, square pyramidal, square planar

Each of the shapes are affected by mainly two things: If they have lone pairs and how many different bonds they have with different atoms.

in addition to knowing the shapes, also know the angles associated with them

There are technically 12 from the 7th E textbook including pentagonal bipyramidal, though I don't think that shape would come up often compared to the other 11.

You can figure out the different shapes based on the number of bonds and lone pairs of the compound. Also, the number of lone pairs of the compound.

Lavelle has covered only 11 shapes and their corresponding angels so I am assuming those will be the only we will need to know for the upcoming test and final.
