MCQ
Diazo coupling is useful to prepare some:
- APesticides
- ✓Dyes
- CProteins
- DVitamins
✓
Answer
Correct option: B.
Dyes
The first use of diazonium salts was to produce water$-$fast dyed fabrics by immersing the fabric in an aqueous solution of the diazonium compound, followed by immersion in a solution of the coupler $($the electron $-$ rich ring that undergoes electrophilic substitution$).$
The major applications of diazonium compounds remains in the dye and pigment industry.
