OR Chem 1 - Unit 3 Exam 2 Review

Front

What are ionic bonds?

Back

Ionic bonds are chemical bonds formed between metals and nonmetals, where electrons are transferred from one atom to another.

Front

Which substance has the highest boiling point at standard pressure?

Back

H2O (water) has the highest boiling point due to strong hydrogen bonding.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

Which substance has the weakest intermolecular forces of attraction?

Back

CH4 (methane) has the weakest intermolecular forces due to its nonpolar nature.

Front

Does HCl have hydrogen bonding?

Back

No, HCl does not have hydrogen bonding because it does not have the necessary structure for it.

Front

What is an alloy?

Back

An alloy is a mixture of two or more metals, or a metal and another element, that has metallic properties.

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 electrons between atoms.

Front

What is the significance of boiling point in substances?

Back

The boiling point indicates the temperature at which a substance transitions from liquid to gas, influenced by intermolecular forces.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bonds are formed between two nonmetals.

Front

What is the role of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; higher electronegativity leads to stronger bonds.
