Example Question #2 :Sat Subject Test In Chemistry

Based on VSEPR theory and electron configurations, which of the following molecules isnotmatched with its correct geometry?

Possible Answers:

- Bent (v-shaped)

- Tetrahedral

- Linear

- Linear

- Trigonal planar

Correct answer:

- Trigonal planar

Explanation:

has three bonding pairs and one non-bonding pair, which is the geometry for trigonal pyramidal, not trigonal planar.

Example Question #1 :Sat Subject Test In Chemistry

What is the molecular geometry of?

Possible Answers:

Trigonal pyramidal

Octahedral

Square planar

Tetrahedral

Square pyramidal

Correct answer:

Square pyramidal

Explanation:

There are six electron domains in.has five bonding and one nonbonding pairs of electrons. The electron domain geometry ofis octahedral. When a molecule has octahedral electron domain geometry and has five bonding and one nonbonding pairs, the molecular geometry is square pyramidal.
