MCQ
Bakelite is obtained from phenol by reacting with:
- A$\left(\mathrm{CH}_2 \mathrm{OH}\right)_2$
- B$\mathrm{CH}_3 \mathrm{CHO}$
- C$\mathrm{CH}_3 \mathrm{COCH}_3$
- ✓$\text{HCHO}$
✓
Answer
Correct option: D.
$\text{HCHO}$
Bakelite was the first plastic made from synthetic components.
It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol $\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}\right)$ with formaldehyde $\text{(HCHO)}.$
