Unit 03 Test Review

Front

What is the boiling point of water compared to methane?

Back

Water has a higher boiling point than methane due to stronger hydrogen bonds compared to methane's van der Waals forces.

Front

What is covalent bonding?

Back

Covalent bonding involves the sharing of electron pairs between atoms.

Front

How can you determine if a molecule is polar or non-polar?

Back

A molecule is polar if it has a net dipole moment due to the presence of polar bonds and an asymmetrical shape; otherwise, it is non-polar.

Front

What type of bond forms between hydrogen (H) and oxygen (O) atoms?

Back

A covalent bond forms between hydrogen and oxygen atoms.

Front

Which element has the greatest electronegativity?

Back

Chlorine (Cl) has the greatest electronegativity.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electron pairs.

Front

What is a polar molecule?

Back

A polar molecule has a partial positive charge on one side and a partial negative charge on the other due to unequal sharing of electrons.

Front

What is a non-polar molecule?

Back

A non-polar molecule has an even distribution of electrical charge, meaning it does not have distinct positive or negative poles.
