Question

An orbital having one rafial nodes and two angular nodes may be:

• A. ${3d}_{xy}$
• B. ${4d}_{yz}$
• C. ${5d}_{x^2-y^2}$
• D. ${4p}_z$

Answer 1

The correct option is B ${4d}_{yz}$

Radial nodes= $n-l-1$

Angular nodes= $l$

$2$ angular nodes means $l=2$

$l=2$ is for $d-$orbitals.

As $1$ radial node is there.

$\Rightarrow n-2-1=1$

$\Rightarrow n=4$

So, the orbital is $4dyz$ .
