Q12 / 155 · WBJEE 2018 · Chemistry

Which of the following electronic configuration is not possible?

A
$n=3 l=0 m=0$
B
$n=3 l=1 m=-1$
Correct answer
C
$n=2.l=0 \mathrm{mm}-1$
D
$n=2, l=1 m=0$

Solution

$n=2,1=0, m=-1$ is not a possible electronie configuration. With $n=2$ and $/-0$, the orbital is having only one $m_{1}$ value i.e. $0 .$ As the value of $m_{1}=-1 t 0+l$ Other options are correct.

Hence, the correct answer is option: 'C'.
