What Are Allotropes? Non-Metals

The video tutorial explores the concept of allotropes, focusing on carbon, oxygen, phosphorus, and sulfur. It explains how different arrangements of atoms in these elements lead to varied physical and chemical properties. For carbon, diamond and graphite are compared, highlighting their structural differences. Oxygen's allotropes, O2 and ozone, are discussed, emphasizing their environmental roles. The video also covers phosphorus allotropes, red and white, and their applications in matches. Lastly, sulfur allotropes, including S8, are introduced, showcasing their unique structures.

What is the primary reason for the different properties of diamond and graphite?

• The number of carbon atoms in each structure

• The presence of impurities

• The type of chemical bonds present

• The arrangement of carbon atoms

Which of the following is a property of ozone that makes it important for Earth's atmosphere?

• It is a greenhouse gas

• It is used in the production of plastics

• It forms a protective layer that insulates the Earth

• It is a major component of breathable air

What is resonance stabilization, as seen in ozone?

• The presence of multiple allotropes

• The formation of a single covalent bond

• The delocalization of electrons across a molecule

• The ability of a molecule to conduct electricity

Why were white phosphorus matches replaced with red phosphorus matches?

• White phosphorus is less flammable

• Red phosphorus is more colorful

• White phosphorus is more flammable and dangerous

• Red phosphorus is cheaper to produce

Which allotrope of sulfur is most commonly known for its bright yellow color?

• S8 octo sulfur

• Trisulfur

• S6 hexa sulfur

• Disulfur
