NEET levelSingle correct optionDifficulty 1 of 3as121

The magnitude of orbital angular momentum of an electron in a d orbital is

A $2 \frac{h}{2 π}$
B $6 \frac{h}{2 π}$
C $12 \frac{h}{2 π}$
D $2 \frac{h}{2 π}$

Answer: B

L = l (l + 1) ℏ

with

l = 2

for d, giving

6 h /2 π

. The option with 2 confuses

L

with

l

or with

m_{l}

.
