Question

The first synthetic dye was invented by ______

• A. Eli Whitney
• B. Johan Tobias Mayer
• C. Sir William Perkin
• D. Sir Issac Newton

Hint:

To remember this discovery, think of William Perkin and his purple dye, Mauveine. This single accidental experiment transformed organic chemistry and changed fashion forever.

Answer 1

The Correct Option is C

Step 1: Historical and Chemical Discovery:
In 1856, an 18-year-old British chemistry student named William Henry Perkin was conducting experiments in his home laboratory. Under the direction of August Wilhelm von Hofmann, Perkin was attempting to synthesize quinine, a valuable and expensive drug used to treat malaria, from coal tar.

Step 2: Accidental Discovery of Mauveine:
Instead of obtaining quinine, Perkin's reaction produced a dark, sticky residue. When he rinsed the flask with alcohol, the solution turned a brilliant, intense purple color. He discovered that this compound could dye silk fibers directly without fading under light or washing. This dye was named Mauveine (or aniline purple), the world's first commercially viable synthetic organic dye.

Step 3: Impact on the Textile and Chemical Industries:
Prior to Perkin's discovery, dyes were sourced from plants or animals (such as cochineal insects or madder roots) and were expensive and prone to fading. Perkin's invention of synthetic mauve dye founded the modern synthetic chemical industry, making vibrant, deep-colored garments accessible to everyone.
