Given below are two statements: Statement I : The energy of 3d orbital is greater than 4p orbital. Statement II : If two orbital have the same value of ( ( n + )), the ortbial with lower value of n will have the lower energy. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth statement I and statement II are correct.
  2. BStatement I is correct but statement II is incorrect
  3. CStatement I is incorrect but statement II is correct.
  4. DBoth statements I and statements II are incorrect.

Correct answer

C. Statement I is incorrect but statement II is correct.

Step-by-step solution

- Statement I: The energy of the 3d orbital is actually lower than the 4 p orbital. This is because the 3d orbital belongs to the third energy level, while the 4 p orbital belongs to the fourth energy level. Hence, this statement is incorrect. - Statement II: According to the ( ( n + )) rule (or Madelung rule), if two orbitals have the same value of (n+ ), the orbital with the lower value of (n ) will have lower energy. This is correct.
