Given below are two statements:
Statement-I: The orbitals having same energy are called as degenerate orbitals.
Statement-II: In hydrogen atom, and orbitals are not degenerate orbitals.
In the light of the above statements, choose the most appropriate answer from the options given
Options
- AStatement-I is true but Statement-II is false
- BBoth Statement-I and Statement-II are true.
- CBoth Statement-I and Statement-II are false
- DStatement-I is false but Statement-II is true
Correct answer
A. Statement-I is true but Statement-II is false
Step-by-step solution
Degenerate orbitals are the orbitals of the same subshell having equal energies. When the electrons of the orbitals are not influenced by any external factors like an electric field or magnetic field, they have same energies.
For a single electron species like hydrogen atom, the energy depends upon the principal quantum number only. Hence, oribitals have same energy. So, statement II is false.
Statement I is correct definition of degenerate orbitals.
Hence, the answer is option A.
