Asked in Premeth Test 18 — Alkyl Halides, Aldehydes and Ketones, Atomic Structure (20 March 2025) 2025

For "f" orbital value of l is:

Correct answer: A. 3

  • A. 3
  • B. 2
  • C. 0
  • D. 1

Explanation

The azimuthal quantum number, represented by the symbol l, defines the shape of the orbital. Each type of orbital has a specific l value: s orbitals have l = 0, p orbitals have l = 1, d orbitals have l = 2, and f orbitals have l = 3. Therefore, for an f orbital, the correct value of l is 3. Options B, C, and D correspond to the azimuthal quantum numbers for d, s, and p orbitals, respectively, and thus are incorrect.

About Quantum Numbers

Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
