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

The number of spherical nodes in 4s orbital is:

Correct answer: B. 3

  • A. 4
  • B. 3
  • C. 2
  • D. 1

Explanation

This is incorrect. The 4s orbital has 3 spherical nodes, not 4. Applying the formula, we get: Number of spherical nodes = n - l - 1 = 4 - 0 - 1 = 3. Therefore, the 4s orbital has 3 spherical nodes. This is incorrect. The 4s orbital has 3 spherical nodes, not 2. This is incorrect. The 4s orbital has 3 spherical nodes, not 1.
