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$(iv)$

$(v)$ Both the carbon are $s{p^2}$ hybridized. Therefore planar.
$C{{H}_{2}}=C\begin{matrix}
