Structural Isomers

[chrisf]

For the chemical formula C₃H₅N, draw three different structural isomers, one in the condensed form, one in line-angle form, and one in three-dimensional representation.

Each isomer should show the nitrogen in a different hybridization.
What is the molecular geometry around each nitrogen in each case?
What orbitals are overlapping to form each bond coming out of the nitrogen?

UPDATE - I've figured out the structures and should be able to easily determine the rest. I'll post my answers to see what people think.

Here's what I came up with.

Here's my complete answer. Does it look reasonable?
