MCQ
The number of unpaired electrons in carbon atom in excited state is
- A$1$
- B$2$
- C$3$
- ✓$4$
✓
Answer
Correct option: D.
$4$
d
(d) ${C_6} = 1{s^2},\,2{s^2}2{p^2}$ (Ground state)
(d) ${C_6} = 1{s^2},\,2{s^2}2{p^2}$ (Ground state)
$ = 1{s^2}\,2{s^1}\,2P_x^1\,2p_y^1\,2p_z^1$ (Excited state)
In excited state no. of unpaired electron is $ 4.$
