JEE MainChemistryStructure of AtomMCQ+4 / −1
The orbital having two radial as well as two angular nodes is :
- A3p
- B5d
- C4d
- D4f
View written solutionFree
Correct answer: B
- Use the formulas for nodes
For an orbital with principal quantum number and azimuthal quantum number :
- Angular nodes
- Radial nodes
We need an orbital having:
- angular nodes
- radial nodes
- Find the required quantum numbers
Since angular nodes , the orbital must be a -orbital.
Now radial nodes should also be :
Substitute :
So the orbital is .
- Check each option
A:
For orbital, .
- Angular nodes
- Radial nodes
So has 1 radial and 1 angular node. Not correct.
B:
For orbital, .
- Angular nodes
- Radial nodes
So has 2 radial and 2 angular nodes. Correct.
C:
For orbital, .
- Angular nodes
- Radial nodes
So has 1 radial and 2 angular nodes. Not correct.
D:
For orbital, .
- Angular nodes
- Radial nodes
So has 0 radial and 3 angular nodes. Not correct.
- Final answer
The orbital having two radial as well as two angular nodes is:
So, Option B is correct.
