Question

Which of the following statements is correct regarding the formation of a sigma bond?

• A. Sideways overlap of orbitals take place
• B. End to end overlap of orbitals take place
• C. Sideways as well as end to end overlap of orbitals take place
• D. None of the above

Answer 1

The correct option is B End to end overlap of orbitals take place

Sigma bond is formed by the overlap of two half filled $s$ - orbitals along the internuclear axis.


Sigma bond is also formed by the head on or end to end overlap of two half filled $s$ and $p$ orbitals or by the head on overlap of two half- filled p-orbitals.
