STANDARD Chemistry Quantum Mechanical Model MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which one is the wrong statement

A

The uncertainty principle is ΔE × Δt ≥ h/4π

B

Half filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement.

C

The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms

D

de-Broglies's wavelength is given by λ = h/mv, m = mass of the particle, v = group velocity of the particle
