Assertion : The spectrum of He^ + is expected to be similar to that...

Assertion : The spectrum of He+\mathrm{He}^{+}is expected to be similar to that of hydrogen.Reason : He+\mathrm{He}^{+}is also one electron system.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion

Step-by-step solution

All species like He+,Li2+,Be3+\mathrm{He}^{+}, \mathrm{Li}^{2+}, \mathrm{Be}^{3+} having one electron are expected to have similar spectrum as that of hydrogen.
