Q9 / 170 · Manipal (MET) 2021 · Chemistry

Which of the following is not possible ?

A
$n=3, l=0, m=0$
B
$n=3, l=1, m=-1$
Correct answer
C
$n=2, l=0, m=-1$
D
$n=2, l=1, m=0$

Solution

When $n=3, l=0,1,2$ and For $\begin{aligned} & l=0, m=0 \\ & l=1, m=-1,0,+1 \\ & l=2, m=-2,-1,0,+1,+2\end{aligned}$ So, for the value $l=0, m$ cannot be -1

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