Ch 6 Review Honors

Front

What is the bond length between carbon and oxygen atoms in CO?

Back

The bond length in CO is shorter than in CO2, CH3O, and H2O.

Front

What results in a covalent bond?

Back

A covalent bond results from the mutual attraction of the nuclei for electrons.

Front

What is a property of covalent compounds?

Back

Covalent compounds typically have low boiling points.

Front

Which compound has the highest boiling point: CBr4, SI6, PF5, or N2?

Back

SI6 has the highest boiling point.

Front

What type of bond exists between two fluorine atoms?

Back

The bond between two fluorine atoms is non-polar.

Front

Define a covalent bond.

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while non-polar covalent bonds have equal sharing.

Front

What is the significance of bond length in molecular compounds?

Back

Bond length affects the stability and reactivity of molecules; shorter bonds are generally stronger.

Front

How does electronegativity affect bond type?

Back

Electronegativity differences determine whether a bond is ionic, polar covalent, or non-polar covalent.

Front

What is the general trend of boiling points in covalent compounds?

Back

Covalent compounds with stronger intermolecular forces generally have higher boiling points.
