Lewis Dot and Molecular Geometry / Shape

Question

What would the shapes be for a central atom with:

1) 4 atoms and 1 lone pair.

2) 5 atoms and 2 lone pairs.

3) 5 atoms and 0 lone pairs.

4) 3 atoms and 2 lone pairs.

5) 4 atoms and 1 lone pair (no, this isn't a mistake. It was placed on the assignment twice)

6) 4 atoms and 2 lone pairs.

Answer 1

This is stuff you just need to learn (memorize); kinda like learning a new language where you have to learn (memorize) vocabulary, etc.

1) 4 atoms and 1 lone pair. - distorted tetrahedron/see saw

2) 5 atoms and 2 lone pairs. - T-shaped(?)

3) 5 atoms and 0 lone pairs. - trigonal bipyramidal

4) 3 atoms and 2 lone pairs. - T-shaped

5) 4 atoms and 1 lone pair - distorted tetrahedron/see saw

6) 4 atoms and 2 lone pairs. - square planar
