QJEEM22Chd9e9: JEE Main 2022 Chemistry - Class 11 JEEM22Chd9e9 Solution: The correct decreasing order of energy for the orbitals having, …

The correct decreasing order of energy for the orbitals having, following set of quantum numbers :

(A) n = 3, l = 0, m = 0

(B) n = 4, l = 0, m = 0

(C) n = 3, l = 1, m = 0

(D) n = 3, l = 2, m = 1

is :

Multiple Choice Options

  • A (D) > (B) > (C) > (A)
  • B (B) > (D) > (C) > (A)
  • C (C) > (B) > (D) > (A)
  • D (B) > (C) > (D) > (A)

Step-by-Step Verified Solution

(A) n+ℓ=3+0=3\mathrm{n}+\ell=3+0=3

(B) n+ℓ=4+0=4\mathrm{n}+\ell=4+0=4

(C) n+ℓ=3+1=4\mathrm{n}+\ell=3+1=4

(D) n+ℓ=3+2=5\mathrm{n}+\ell=3+2=5

Higher n+ℓ\mathrm{n}+\ell valuc, higher the encrgy & if same n+ℓ\mathrm{n}+\ell value, then higher n\mathrm{n} value, higher the energy.

Thus : \mathrm{D}>\mathrm{B}>\mathrm{C}>\mathrm{A} .
