Assertion: Total number of orbitals asso...

Assertion: Total number of orbitals associated with principal quantum number n=3 is 6.
Reason : Number of orbitals in a shell equals to 2n.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
D
Both assertion and reason are false. Total number of orbitals associated with Principal quantum number n=3 is 9.one 3s orbital + three 3p orbital + five 3d orbitals.
`therefore` Therefore there are a total number of nine orbitals.
Number of orbitals in a shell equals to `n^2`.
