Question

Identify the electron pair geometry and the molecular structure of each of the following molecules:

a) Tetrahedral, Trigonal Pyramidal
b) Linear, Linear
c) Trigonal Bipyramidal, T-shaped
d) Trigonal Planar, Bent

Answer 1

The electron pair geometry and molecular structure of the given molecules vary based on the number of electron pairs and lone pairs.

Step-by-step explanation:

For the given molecules:

1. (a) Tetrahedral, Trigonal Pyramidal
2. (b) Linear, Linear
3. (c) Trigonal Bipyramidal, T-shaped
4. (d) Trigonal Planar, Bent

The electron pair geometry refers to the arrangement of electron pairs around the central atom, while the molecular structure refers to the arrangement of atoms in a molecule. In all cases, the electron pair geometry is determined by the number of electron pairs around the central atom, and the molecular structure is determined by the number of lone pairs and bonding pairs. The examples given exhibit different geometry and structures, which can be determined based on the number of regions of electron density and lone pairs.
