He says the nitrogen is trigonal bipyramidal, but isn't there 4 electron pairs, not 5? So why isn't it tetrahedral?
Thanks

it's trigonal pyramidal, as the others have stated.
the shape of the molecule is not tetrahedral, though it has 4sp3 hybridised orbitals. This is because for the shape of the molecule, only the sides with the bonds are considered. For NH3, nitrogen has 3 bonds with 1 H atom each and 1 lone pair. The lone pair is not exactly considered as one vertex of the tetrahedral, as it is sort of considered to be occupying less space as there is no bond.
The electron geometry of the molecule determined its shape (tetrahedral), but due to the lone pair, the top of the tetrahedral is sort of shaved off, thus it becomes trigonal pyramidal.

it is trigonal pyramid, not bypiramid.
it's not tetrahedral because angles don't match. in NH2OH angle is 107 degrees and in tetrahedra is 109,5. tetrahedra is trigonal pyramid with all angles equal, here in NH2OH 3 nagles are 107 degrees (angle HNH and ONH), and angle electron pair - N - H is greater

The electron geometry will be tetrahedral, but the shape of the molecule will be a trigonal pyramid not trigonal bipyramidal
