: Accelerates the screening of unique molecular structures against diseases, streamlining pharmaceutical R&D. Top Strategies for Solving This Passage
Unlike traditional synthetic organic chemistry—where scientists painstakingly create one single molecule at a time—combinatorial chemistry functions as a specialized . It utilizes mathematical concepts of permutations and combinations. By reacting a broad set of starting materials in a single process, scientists can synthesize millions of unique compounds simultaneously, opening up limitless chemical possibilities. 3. Transforming Commercial Drug Discovery

How do some orchids achieve pollination without producing nectar?
The text explains how combinatorial chemistry has become a "buzzword" in biotechnology and agrochemicals. It describes the transition from traditional, slow chemical synthesis to "high-throughput" methods where thousands of compounds can be created simultaneously. Key themes include the use of (tea-bag method) for managing chemical reactions and the mathematical complexity of molecular combinations. Answer Key
The text explicitly mentions the year and the names of the chemists who first isolated the specific volatile organic compound (VOC), marking the historical origin of the research.
