Unit 9 Molecular Orbitals

Front

What is a π (pi) bond?

Back

A π (pi) bond is the result of the sidewise overlap of two parallel p orbitals.

Front

What type of bond is formed by s orbital-s orbital overlap?

Back

A σ (Sigma) bond.

Front

True or False: A molecular orbital that can be occupied by two electrons of a covalent bond is called a bonding orbital.

Back

True.

Front

Which bond is stronger: σ Bond or π Bond?

Back

σ Bond.

Front

What shape is an s orbital?

Back

An s orbital is shaped like a sphere.

Front

What is the primary characteristic of a σ (Sigma) bond?

Back

A σ bond is formed by the end-to-end overlap of orbitals.

Front

What is the primary characteristic of a π (Pi) bond?

Back

A π bond is formed by the sidewise overlap of orbitals.

Front

How many electrons can occupy a single molecular orbital?

Back

A single molecular orbital can be occupied by a maximum of two electrons.

Front

What type of overlap occurs in a σ bond?

Back

End-to-end overlap of orbitals.

Front

What type of overlap occurs in a π bond?

Back

Sidewise overlap of two parallel p orbitals.
