Assertion : Si-Si bonds are much stronger than Si-O bonds. Reason :...

Assertion : Si−Si\mathrm{Si}-\mathrm{Si} bonds are much stronger than Si−O\mathrm{Si}-\mathrm{O} bonds. Reason : Silicon forms double bonds with itself.

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

D. If both assertion and reason are false.

Step-by-step solution

Si−Si\mathrm{Si}-\mathrm{Si} bonds are weaker than Si−O\mathrm{Si}-\mathrm{O} bonds. Si has no tendency to form double bonds with itself.
