Question

Which of the following is often termed as diagonal hybridisation?

• A. $sp$
• B. $s{p}^2$
• C. $s{p}^3$
• D. None of these

Answer 1

The correct option is A $sp$

$sp$ hybridisation arises due to mixing of one $s$ and one $p$ orbital of the valence shell giving rise to two equivalent $sp$ hybrid orbitals.
The $sp$ hybrid orbitals are directed at ${180}^o$ with respect to each other and hence termed as diagonal hybridisation.
