MCQ
Which of the following compounds are antiaromatic
- A$(I)$ and $(V)$
- B$(II)$ and $(V)$
- C$(I)$ and $(IV)$
- ✓$(V)$ and $(VI)$
✓
Answer
Correct option: D.
$(V)$ and $(VI)$
d
For a compound to be aromatic it must have $(4n + 2)\pi e^-$ and system should be planar where $n$ is an integer. $(V)$ and $(VI)$ both have $4\, e^-$ and planar structure. Hence are Antiaromatic
