Question

Assertion :In tetrahedral hybridization ie. in $s{p}^3$ hybridization all p-orbitals are involved and no p-orbital is left for forming $\pi$-bonds. Reason: Central atom can not form double bonds in the molecules or species having $s{p}^3$ hybridization.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion.
• C. Assertion is correct, but Reason is incorrect.
• D. Assertion is incorrect, but Reason is correct.

Answer 1

The correct option is C Assertion is correct, but Reason is incorrect.

Assertion : It is correct statement because all three p-orbitals are involved in sp${}^3$ hybridisation and thus no p-orbital is left for side wise overlapping.
Reason: XeO${}_3$ is sp${}^3$ hybridisaed and Xe form three double through p$\pi$-d$\pi$ overlapping.
