Chemistry II Unit 3 Review

Front

What is a pi bond?

Back

A pi bond is formed by the side-to-side overlap of p orbitals.

Front

Which noble gas has the highest boiling point?

Back

Xenon (Xe) has the highest boiling point among noble gases.

Front

What is the bonding situation in the nitrite ion (NO2-)?

Back

In the nitrite ion, both bonds are the same because of resonance.

Front

How many sigma bonds are present in a triple bond?

Back

A triple bond contains 1 sigma bond.

Front

What is the bond strength between carbon and oxygen in carbonate ions?

Back

The bond strength is C-O (between single and double bond).

Front

Define a sigma bond.

Back

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

Front

What is resonance in chemistry?

Back

Resonance is the concept that some molecules can be represented by two or more valid Lewis structures.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the electrons in the outermost shell that participate in chemical bonding.

Front

Explain the difference between single, double, and triple bonds.

Back

Single bonds involve one pair of shared electrons, double bonds involve two pairs, and triple bonds involve three pairs.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons.
