MCQ
Which compound is different from the others?
- AMethyl ethyl ketone
- BPentan - 2 - one
- C2 - Pentanone
- DMethyl propyl ketone
✓
Answer
- Methyl ethyl ketone
Explanation:
Methyl ethyl ketone $(\text{CH}_3-\text{ C}-\text{CH}_2-\text{CH}_3)\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ||\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{O}$ is different from the others.
Methyl ethyl ketone (also called butanone) contains 4C atoms.
Pentan-2-one, 2-pentanone and methyl propyl ketone are different names of same compound $(\text{CH}_3-\text{ C}-\text{CH}_2-\text{CH}_2-\text{CH}_3)\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ||\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{O}$which contains 5C atoms.
