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 assertionB. If both assertion and reason are true but reason is not the correct explanation of the assertionC. If assertion is true but reason is falseD. If the assertion and reason both are false

Answer» Correct Answer - 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`.
