• Noun:
  • Trong phản ứng này, monomer kết hợp tạo thành nhị trùng. (In this reaction, the monomers combine to form a dimer.)
  • Nhị trùng này có tính chất hóa học khác với monomer. (This dimer has different chemical properties from the monomer.)

Advanced Usage

• The term is used almost exclusively in scientific fields like chemistry, biochemistry, and polymer science to describe a specific type of molecular structure.

Variants and Related Words

• Đa trùng (n): polymer (a compound of many repeating monomers).
• Tam trùng (n): trimer (a compound of three identical monomers).
• Monome (n): monomer (a molecule that can bond with others to form a polymer).
