高考化学：物质结构与性质

A high-school chemistry practice set on molecular structure and properties: hybridization theory (sp3/sp2/sp), molecular polarity, crystal types (atomic, ionic, molecular, metallic), and intermolecular forces including hydrogen bonding and van der Waals forces.

• Determine hybridization type and molecular geometry from Lewis structures
• Judge molecular polarity from symmetry and bond polarity
• Classify crystal types and compare their melting points
• Explain the role of hydrogen bonds and van der Waals forces in physical properties
