MCQ
Examine the following common chemical structures to which simple functional groups are often attached Which of these systems have essentially planar geometry
- A$(i)$ and $(v)$
- B$(ii)$ and $(iii)$
- C$(ii)$, $(iii)$ and $(iv)$
- D$(iv)$
✓
Answer
$(a)$ $(i)$ Benzene and its derivatives are always planar because all the carbon in benzene are $s{p^2}$ hybridized.
$(v)$ Both the carbon are $s{p^2}$ hybridized. Therefore planar.
