Question

Which of the following overlapping can be of two types either $(\sigma ,\pi )$ or $(\pi ,\delta )$ or $(\sigma ,\delta )$ with appropriate internuclear axis as per the requirement of overlapping?

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

Answer 1

Answer: (A)

$d_{x^2-y^2}+d_{x^2-y^2}$

$\delta$ - bond can only be formed by faceways overlapping of two $d_{x^2-y^2}$ orbitals. Side ways overlapping of these orbitals from $\Pi -$ bond.
