Question

Which of the following overlaps gives a $\sigma$ bond with x as the internuclear axis?

• A. $p_z$ and $p_z$
• B. s and $p_z$
• C. s and $p_x$
• D. $d_{x^2-y^2}$ and $d_{x^2-y^2}$

Answer 1

The correct option is C s and $p_x$

Sigma bond is formed by the overlap of s-s orbital and head on overlap of s-p and p-p orbital,
