Q36 / 180 · AIIMS 2013 · Chemistry

Assertion : Number of radial and angular nodes for $3 p$-orbital are 1,1 respectively. Reason : Number of radial and angular nodes depends only on principal quantum number.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • Correct answer
    C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

For $3 p$-orbital, number of radial nodes $=n-l-1=3-1-1=3-2=1$ Number of angular nodes $=l=1$ Number of radial and angular nodes depend on both $n$ and $l$.

Hence, the correct answer is option: 'C'.
