#### Answer:

Here's what I get for 1. and 2.

#### Explanation:

The Lewis structure of

(From saylordotorg.github.io)

It has 3 bond pairs and one lone pair for a **steric number** (SN) of 4.

Hence its **electron geometry** is tetrahedral.

(From OpenStudy)

The **molecular shape** ignores the lone pair and refers only to the bonds.

Thus, the VSEPR shape of **trigonal pyramidal**.

The Lewis structure of

It has 5 bonding pairs and no lone pairs, so its electron geometry and molecular geometry are the same.

The VSEPR shape is **trigonal bipyramidal**.
